    Reading Time: 5 minutes

    The digital revolution has reshaped every facet of our lives, underscoring the need for robust computing education. At the Raspberry Pi Foundation our mission is to enable young people to realise their full potential through the power of computing and digital technologies. Since starting out in 2008 as a UK-based educational charity, we’ve grown into a global leader in advancing computing literacy.

    An educator and students working on a coding task.

    At the heart of our efforts lies a simple yet powerful vision: to ensure every young person develops the knowledge, skills, and confidence to use digital technologies effectively. This includes understanding societal and ethical issues, using technology for creative problem solving, and fostering a mindset of adaptability that will enable them to thrive amid rapid technological change.

    A vision for global computing education

    To realise this vision, we developed The Computing Curriculum (TCC). Launched in 2018 as part of the UK’s National Centre for Computing Education, TCC is a comprehensive set of free teaching resources tailored for students aged 5–16. Over the years, the curriculum has evolved through rigorous testing and teacher feedback, which has helped to make it one of the most effective and inclusive computing education tools globally.

    Contextualising computing education for India

    India’s vast diversity — in languages, social and economic contexts, and educational infrastructure — creates unique challenges and opportunities. As a result, we at the Raspberry Pi Foundation have adapted and localised our computing curriculum to meet the needs of Indian students. Collaborations with the Telangana Social Welfare Residential Educational Institutions Society (TGSWREIS) and the Odisha Mo School programme have been pivotal in this endeavour.

    Modelling data using a spreadsheet (Grade 9)
    Creating media — audio production (Grade 7)

    In Telangana, we adapted TCC to create a 70+ hour computing curriculum designed for government schools with limited resources. Similarly, in Odisha, elements of this curriculum have been tailored to develop Kaushali, an IT and coding curriculum for over 8,000 state schools. This localised approach ensures that computing education becomes accessible and relevant for students across India.

    A curriculum designed for impact

    The computing curriculum for India spans Grades 6 to 10 (age group 11-16) and is structured to ensure progressive learning. Students revisit foundational concepts repeatedly, building on prior knowledge as they advance through the grades. The curriculum emphasises forming a strong understanding of concepts over rote learning and integrates research-informed pedagogical approaches.

    We tested our localised curriculum resources in Telangana Coding Academy, and there was lots of positive feedback from educators and observers. Overall, the educators were happy with the content format, and the observers noted that students enjoyed learning and completing the activities. This was also evident from the student discussion notes and student survey responses.

    “[…] this content is more than what we are expecting for the school years[…] this time they [are] having [a] practical session. So they are very happy to do it and whenever they are free[,] they will come and ask us. ‘[C]an you take [an] extra class for us?’” – Educator

    “[…] They are very [appreciative of] the content and [t]hey [are] learning very well, and the response is very good.” – Educator

    Key features of the curriculum:

    • Tailored content: Materials are customised to align with the proficiency levels and contexts of Indian students, ensuring accessibility
    • Localised examples: By incorporating culturally relevant examples, students find the learning experience relatable and engaging
    • Simplified language: Designed for students who may lack confidence in English, the curriculum employs clear and concise language for better comprehension
    • Hands-on learning: Practical activities, including projects and model creation, solidify understanding and foster creativity
    • Ready-to-use resources: Teachers are equipped with lesson plans, presentations, worksheets, and activity sheets, reducing preparation time and enhancing delivery

    Learning objectives:
    The curriculum focuses on equipping students with:

    • An understanding of digital systems and their impact on people and society
    • Computational thinking and problem-solving skills for real-world applications
    • Confidence and knowledge to become creators and innovators
    • Awareness of digital citizenship and responsible technology use

    Curriculum structure:
    Each academic year includes 30–34 sessions, each lasting 45–60 minutes. Lessons are structured into deliverable units comprising detailed plans, presentations, and worksheets. Both plugged (computer-based) and unplugged (activity-based) learning methods are used, with a 60:40 ratio, ensuring balanced and inclusive learning experiences.

    Sample progression across grades:

    Curriculum highlights

  • Does your sample contain DNA or RNA? DIYNAFLUOR can tell you on a budget

    Does your sample contain DNA or RNA? DIYNAFLUOR can tell you on a budget

    Reading Time: 2 minutes

    Lab equipment is — traditionally at least — tremendously expensive. While there are understandable reasons for those costs, they are prohibitive to anyone operating outside of a university or corporate lab. But as the “citizen science” movement has grown, we’ve seen more and more open-source and affordable designs for lab equipment hitting the internet. The latest will be interesting to anyone who wants to do work with DNA or RNA: the DIYNAFLUOR

    DINYAFLUOR stands for “DIY Nucleic Acid Fluorometer,” which describes this device’s function. A fluorometer is a piece of equipment the measures the amount of light emitted by anything that fluoresces. In this context, that would be a reagent that increases in fluorescence when it comes into contact with the nucleic acid in DNA or RNA. The more light the fluorometer detects, the more nucleic acid is present in the sample. Sensitivity is important, which is part of the reason that fluorometers are expensive (usually several thousand dollars for basic models).

    The DIYNAFLUOR, on the other hand, only costs about $40 to build. It works with both custom and commercially made fluorescent DNA quantification kits and can measure DNA on the scale of nano-micrograms.

    This is affordable because its designers built it around off-the-shelf components that are easy to source and a 3D-printable enclosure. The primary component is an Arduino UNO Rev3 board, which looks at the sample through a TSL2591-based light sensor. An LED puts out 470nm light to excite the reagent and optical filters remove the unwanted wavelengths. User-friendly software with a simple GUI lets citizen scientists take measurements and record data directly to their computers.

    This may be a specialized device with narrow appeal. But for those who want to work with DNA or RNA outside of a “real” lab, the cost and performance of DIYNAFLUOR is unbeatable.

    Managing shared spaces, especially meeting rooms, can be a headache in busy offices. At Arduino, we’ve experienced it firsthand in our flexible and dynamic offices around the world – where colleagues could often be seen wandering around with their laptops, trying to find a quiet place for videocalls or brainstorming sessions. 

    We started with a simple shared Google Calendar, but as we often do, we took it a step further by creating an innovative solution – using Arduino GIGA R1 WiFi and GIGA Display Shield.

    Open the door to better room booking 

    Our engineers developed a physical device that can be conveniently installed next to every meeting room door, using the Arduino GIGA and GIGA Display Shield. The device connects seamlessly with Google Calendar APIs, allowing users to check room availability and book a space directly from the touchscreen. The APIs are managed by a custom Python® application that processes Google Calendar data and updates the corresponding IoT Thing in Arduino Cloud.

    No more knocking on doors or interrupting meetings to check if the room is free! It’s all displayed in real-time, and booking is just a tap away. And, of course, everything is built with data privacy in mind.

    To power the user-friendly interface we used LVGL, the “light and versatile visual library” perfect for building custom GUIs. We also leveraged Squareline Studio – because sometimes coding just feels like too much work – to easily design the display’s look and feel. 

    For the finishing touch, we even created a custom 3D-printed case (for which you can just download the STL file right here).

    Take it to the next level with automation

    But why stop at meeting room booking? With this phygital system, you can integrate sensors to collect additional data like room temperature, humidity and lighting, automating systems to improve comfort and energy efficiency. 

    Get started today

    Built on two of Arduino’s most advanced products, the Arduino GIGA and GIGA Display Shield, this solution opens endless possibilities for automation and customization in your office.

  • Exploring Alvik: 3 fun and creative projects with Arduino’s educational robot platform

    Exploring Alvik: 3 fun and creative projects with Arduino’s educational robot platform

    Reading Time: 3 minutes

    Alvik is cute, it’s smart, it’s fun… so what can it actually do? 

    To answer this question, we decided to have fun and put the robot to the test with some of the most creative people we know – our own team! A dozen Arduino employees volunteered for a dedicated Make Tank session earlier this fall, and came up with a few great in-house projects for us to share – and you to try! 

    We were so happy with the creative and engaging ideas that we took them on the road for the Maker Faire Rome 2024: they were a hit and attracted many curious visitors to the Arduino booth.

    Hello, Alvik!

    This interactive project, created by Christian Sarnataro and Leonardo Cavagnis, brings to life Alvik’s friendly personality. By waving your hands in front of a Nicla Vision camera, you trigger a cheerful “big hands” gesture in response: it’s Alvik’s way of welcoming newcomers to robotics!

    Why it’s great: The project highlights Alvik’s ease of use and intuitive interactivity, while demonstrating how advanced learners can tap into the robot’s AI capabilities to create meaningful, engaging robotic experiences.

    Robo-Fight Club

    Developed by Davide Neri and Alexander Entinger, this competitive game turns Alvik into a feisty battling robot. Participants control their Alvik to push opponents out of the arena, while trying special moves like “yellow-banana” for spins, “green-slime” to reverse controls, and “blue-ice” to freeze competitors for five seconds. Any robot stepping out of the arena automatically loses the match.

    Why it’s great: Robo-Fight Club demonstrates how Alvik can be used for multiplayer, interactive gaming experiences while teaching users about programming logic and control systems.

    Alvik Mini City

    In this project by Giovanni Bruno, Julián Caro Linares, and Livia Luo, Alvik works tirelessly in a mini city, moving balls from one floor to another. The project showcases how robotics can assist in repetitive and potentially hazardous tasks, inspiring us to imagine practical applications for robotics in their daily lives.

    Why it’s great: This project emphasizes how Alvik is more than just an educational robot – it’s a tool for exploring real-world use cases in automation and problem-solving.

    Your turn!

    Alvik is the perfect companion to learn coding and robotics because it’s easy to get started with, but powerful enough to support complex projects. With the option to program using block-based coding, in MicroPython or the Arduino language, everyone from beginners to advanced users can choose the environment that suits their needs best!

  • UNO Rev3 or UNO R4? Choosing the perfect Arduino for your project

    UNO Rev3 or UNO R4? Choosing the perfect Arduino for your project

    Reading Time: 5 minutes

    The Arduino UNO is legendary among makers, and with the release of the UNO R4 in 2023, the family gained a powerful new member. But with two incredible options, which UNO should you pick for your project? Here’s a breakdown of what makes each board shine, depending on your needs, skills, and goals.

    Why the UNO Rev3 is still a go-to classic

    The UNO Rev3 has been around for over a decade, earning its reputation as a solid, reliable board perfect for beginners. Simple, robust, and versatile, it’s the “base camp” of the Arduino ecosystem. Its 8-bit architecture makes it straightforward to understand exactly what’s happening in your code. 

    Applications and ideal uses 

    The UNO Rev3 is fantastic for projects like controlling LEDs, motors, and simple sensors – as well as any of the 15 projects included in our best-selling Arduino Starter Kit.

    Its ability to handle a higher current directly from each pin makes it ideal for connecting power-hungry sensors or motors without needing extra components. It’s also compatible with an enormous number of sketches and libraries that have been built around it over the years.

    One key advantage? The microcontroller on the UNO Rev3 can be removed, allowing you to use it independently – a feature that many seasoned users love.

    Over the years, users have pushed it to the limit to create some pretty impressive applications: a remarkably powerful library for audio, an interactive crypto-mining tool, and even a whole BASIC computer that you can hang around your neck like a badge!

    The UNO R4 was designed for the modern maker

    The UNO R4 builds on everything makers love about the Rev3, adding features that bring it up to speed with the needs of today’s tech. Its 32-bit Arm® Cortex®-M4 guarantees significantly faster processing power and can handle more advanced projects. It comes in two versions: the UNO R4 Minima for essential functionality and the UNO R4 WiFi for Internet-connected projects.

    The latter is the brains of the Plug and Make Kit: the easiest way to go from zero to tech hero, with step-by-step tutorials to create a custom weather station, a video game controller, a smart timer and so much more!

    Advanced features for new possibilities

    The UNO R4 packs in features that are groundbreaking for the UNO family:

    • 12-bit DAC: Enables analog output for audio waveforms or other analog components without external circuitry.
    • CAN bus: Ideal for connecting multiple devices in robotics or automotive projects.
    • Wi-Fi® and Bluetooth® on the R4 WiFi model: Easily build IoT projects and connect to the Arduino Cloud to control your devices remotely.
    • Enhanced Diagnostics: The R4 WiFi includes an error-capturing mechanism that helps beginners by identifying issues in the code, a fantastic learning tool.

    Applications and ideal uses 

    With increased memory and processing power, the UNO R4 is perfect for projects that require complex calculations or manage multiple processes. Think IoT, data sensing, automation systems, creative installations or scientific equipment where precise measurements and real-time adjustments are key.

    What’s more, the UNO R4 has the capability to leverage AI – and our community has jumped at the chance of exploring whole new realms. One user built a gesture recognition system made of cardboard, another added smart detection to a pet door to always know if their cat was home or not, and another yet came up with a great tool to always know what song is playing.
    Not to mention the possibilities for advanced animations like this one – inspired by Bad Apple – developed thanks to the LED matrix right on the UNO R4.

    Is a 32-bit MCU always better than an 8-bit?

    The short answer is, no. We believe the best solution is always determined by the requirements of the project at hand: bigger, faster, more powerful or more expensive is not always better.

    8-bit microcontrollers process data in 8-bit chunks, which limits the size of numbers they can handle directly to values between 0 and 255 (or -127 and 128). This limitation makes them best suited for applications with minimal data processing needs, such as basic tasks like toggling LEDs or controlling simple sensors. However, they also tend to be more affordable and to consume less power, making hardware design less expensive, and have a simpler architecture, which translates to easier programming. So, if you are still learning the basics and need the most straightforward tool, or you are tackling a project with minimal requirements, an 8-bit MCU is not only all you need, but probably your best option.

    On the other hand, if you need to work on much larger numbers and perform data-heavy calculations, 32-bit microcontrollers can handle advanced applications like image processing and real-time analytics. The difference is not just 4-fold going from 8 to 32: it’s a huge jump from 255 to 4,294,967,295! Almost by definition, any solution that requires this kind of performance will be more complex to design and program, require more memory, and consume more power, often affecting battery life. The upside, of course, is the incredible potential of what you can achieve!

    Compatibility and transitioning from UNO Rev3 to UNO R4

    If you already have experience with the UNO Rev3 and are considering the R4, but have concerns about compatibility, rest assured: they have the same form factor, pinout, and 5V operating voltage. This makes it easy to transfer accessories such as shields from one to the other. 

    On the software side, tutorials and projects are often compatible. We have even created a GitHub repository where you can check compatibility for libraries with the new R4 (and even help us update information or add new R4-friendly versions). This is part of the effort we share with our community to make sure that transitioning to the UNO R4 – if you choose to do so – is as seamless as possible.

    Which Arduino UNO should I choose?
    UNO Rev3 UNO R4
    • Best for beginners or those working on foundational projects.

    • Great for educational settings, where understanding core programming concepts and hardware interactions are the focus.

    • Ideal if you need a reliable, budget-friendly, no-frills board with vast project resources available online.

    • Perfect for advanced users or beginners looking to push boundaries with more complex projects.

    • Best for IoT, data-intensive, or networked applications that require more processing power.

    • A smart choice if you’re experimenting with new peripherals like CAN bus, DAC, or Wi-Fi/Bluetooth connectivity.

    Choose your UNO and start creating!

    Whether you choose the classic UNO Rev3 or the more recent UNO R4, you’re joining a global community of makers, educators, and inventors who love to create. Both boards offer incredible opportunities, each tailored to different stages and styles of making.

  • Turn your old Android smartphone into an Arduino screen with the RemoteXY app

    Turn your old Android smartphone into an Arduino screen with the RemoteXY app

    Reading Time: 2 minutes

    Each component you add to your Arduino project increases its complexity and the opportunity for mistakes. But most projects require some “auxiliary” hardware — components that you use to interact with the Arduino or to help it do the job you’re asking of it. Buttons and displays are great examples. But as Doctor Volt demonstrates in his most recent video, you can replace both of those with the high-quality touchscreen on your old Android smartphone using the RemoteXY app.

    You likely learned early in your Arduino journey that the serial connection between the Arduino development board and a PC is very handy. It lets the Arduino output information and also lets you input commands. But an entire computer (even a laptop) is pretty bulky and requires a lot of power. The RemoteXY app, available for Android devices, lets you use your smartphone to do the same job.

    Even better, you can use the RemoteXY app with an Arduino library to get an interface much more sophisticated than a normal serial terminal. The app still communicates with the Arduino via serial behind the scenes, but it uses that data to enable nice touchscreen-friendly GUI controls, graphs, and more. 

    For that to work, you need a way for your Android smartphone to establish a serial connection with your Arduino board. That is easy to do using an OTG cable with a USB-to-Serial adapter. Together, those let your smartphone talk to your Arduino just like your PC does. Doctor Volt’s video walks you through setting up and using the RemoteXY Arduino library and how to configure the app.

    [youtube https://www.youtube.com/watch?v=d93kF9tAtxc?feature=oembed&w=500&h=281]

    In a short amount of time, you’ll get a user-friendly interface for your project on the smartphone’s high-resolution touchscreen.

  • This nature-inspired display reacts to ambient sounds

    This nature-inspired display reacts to ambient sounds

    Reading Time: 2 minutes

    We all need ways to calm down and relax, and few things are as effective as nature itself. Taking inspiration from organic patterns and smooth, flowing waves, dzeng on Instructables has built an LED wall light that responds in real-time to the sounds within a room.

    The project started out as a 2D vector graphic that featured several overlapping, organic leaf patterns arranged within a circle. This pattern was then etched onto a piece of clear acrylic via a laser cutter before being attached to a blue-painted base. For the lighting effects, dzeng added an LED strip between the two layers before connecting it to an Arduino Nano ESP32.

    The reactive lighting effects are provided by the Nano ESP32’s sketch, which maintains two variables: brightness and delay. Every loop, the current sound levels are read from a microphone and averaged before being mapped onto the aforementioned values. Finally, the currently-illuminated LED is shifted by one position on the strip and the calculated brightness is applied.

    To see it and the entire design process, you can view dzeng’s tutorial here on Instructables.

  • Wax: digital music manager

    Wax: digital music manager

    Reading Time: 4 minutes

    Wax differs from most existing music managers in three ways. Instead of individual tracks, music is catalogued as ‘works’ – such as an album, a symphony, an opera, etc. Secondly, works are categorised by genre, but it also allows you to tag works in a way that is relevant to the genre too; symphonic works can include composer and conductor, while pop music comes with the group and title.

    The final feature is that it will start playing music as soon as you’ve given it enough requirements (in the form of metadata), which you can then change on the fly.

    Multi-core wonder

    Wax is specifically designed for Raspberry Pi 4 because of its quad-core processor. “Wax uses one core to run the user interface, one for playing, one for ripping, and the fourth for time-consuming tasks like fetching metadata from the cloud, like MusicBrainz and Cover Art Archive,” Jeffrey says. “Many audiophiles worry needlessly that burdening a processor involved in playing a sound file can impair the quality of the sound it produces. The multi-processing architecture of Wax obviates this concern as the core responsible for playing the music is not simultaneously performing any other tasks.”

    As a 2TB SSD is being used for storage, you only need normal sized SD card for Raspberry Pi. Jeffrey has used 2GB here. The SSD goes into the underside of the Argon ONE case, and connects via a USB 3.0 adapter

    From the app you can select music starting by genre. “Works by the same composer are listed together,” Jeffrey tells us. “Likewise, multiple versions of each work are listed together. This hierarchical sorting makes it easy to survey the collection for the desired recording – possibly one that you forgot you had. Wax also provides incremental search if you already have a specific work in mind.”

    Individual tracks or even the entire work can be added to the queue. You can also group tracks within a work – perhaps to represent the acts of an opera. “The other interesting feature is that the values in any column can alternatively be represented as a filter button,” Jeffrey continues. “[I can convert] the ‘subgenre’ field to a filter button by dragging the column header to the filter button area. Selecting a value with the filter button removes works from the list that do not match that value.”

    Dive deeper

    While the ‘gears and levers’ are usually hidden, you can enter a robust edit mode that lets you customise metadata, as well as creating new metadata for works. You can use the metadata downloaded from the online sources when creating and editing too.

    Specific data is used to filter inside genres – the categories of data can be edited too. “WaxConfig is a separate program used for configuring Wax,” Jeffrey says. “Most importantly, this is where you specify genres, including their name and the primary and secondary keys. The Info page provides information about your collection, including the number of works in each genre.”

    You can see an example of this in the image to the left. Jeffrey has put together a very in-depth guide on how to install and setup Wax, as well as going into more depth on how to use it. Performance on Raspberry Pi 4 is good too, especially on Jeffrey’s setup.

    If you need to dive deeper to edit the tags for genres, you’re able to do that with Wax-Config

    “I run Wax on a Raspberry Pi 4 with 4 GB of RAM,” Jeffrey tells us. “I use the NanoSound One DAC with the Argon One M.2 case. The NanoSound One DAC uses the TI PCM5122 DAC for high-quality audio output – 112 dB SNR. The Argon case makes it possible to integrate a 2TB SSD which I use for storing my sound archive.”

    Even with the high-power audio hardware and no active cooling, the CPU temperature only reached 45C, with a CPU load of 2.4 (of a theoretical maximum of 4.0 due to the quad-core architecture). He even reckons a 2GB Raspberry Pi would do the job just fine.

    “Wax makes it easy to find and appreciate the music I want to hear,” Jeffrey says. “Finding a recording of a specific work was often hard and always inconvenient when I had to sort through thousands of LPs and CDs. With Wax, I can make a selection from the comfort of my listening position. I sacrifice nothing for this convenience because Wax presents all the information I need to appreciate the recording — artist names, for example — and I am able to explore further, as I used to do by reading record jackets or CD liner notes, by accessing Wikipedia and liner notes in Wax from the comfort of my listening position. Instead of a wall full of recordings, my entire collection now fits in a tiny box powered by a Raspberry Pi.”

    Move Mario remotely with this online N64 controller system

    Reading Time: 2 minutes

    For obvious reasons, video game console controls provide input commands directly to the console. Modern consoles may do so wirelessly, but the effect is the same: direct input. But what if you connected a “controller” to the internet? Then you could play from anywhere and that is exactly what Redditor Lovelyroyalette achieved with this Arduino Due-based N64 controller.

    The N64 controller communication protocol has been well-documented for decades now and is pretty easy to replicate using an Arduino. In fact, there is even a handy library available (called N64Controller) that makes that simple to achieve. Connect a few wires and it will send commands to the N64 like they’re coming from a real controller.

    Normally, people use that functionality to build their own custom N64 controllers. But Lovelyroyalette chose to do something a little different and connected the Arduino Due to their laptop, which runs a server hosting a web interface where visitors can input controller commands. Push “A” on that interface and the laptop will tell the Due to send the “A” command to the N64, causing Mario to jump.

    Not only is that neat from a technical standpoint, but it has some practical uses. The most obvious is to allow remote play — including remote multiplayer sessions in Goldeneye. With a video capture card, the web interface can display the game for remote players to see. This also has interesting applications for streamers, who could, for instance, let the chat send controller commands for some added interactivity.

  • How can we teach students about AI and data science? Join our 2025 seminar series to learn more about the topic

    How can we teach students about AI and data science? Join our 2025 seminar series to learn more about the topic

    Reading Time: 4 minutes

    AI, machine learning (ML), and data science infuse our daily lives, from the recommendation functionality on music apps to technologies that influence our healthcare, transport, education, defence, and more.

    What jobs will be affected by AL, ML, and data science remains to be seen, but it is increasingly clear that students will need to learn something about these topics. There will be new concepts to be taught, new instructional approaches and assessment techniques to be used, new learning activities to be delivered, and we must not neglect the professional development required to help educators master all of this. 

    An educator is helping a young learner with a coding task.

    As AI and data science are incorporated into school curricula and teaching and learning materials worldwide, we ask: What’s the research basis for these curricula, pedagogy, and resource choices?

    In 2024, we showcased researchers who are investigating how AI can be leveraged to support the teaching and learning of programming. But in 2025, we look at what should be taught about AI, ML, and data science in schools and how we should teach this. 

    Our 2025 seminar speakers — so far!

    We are very excited that we have already secured several key researchers in the field. 

    On 21 January, Shuchi Grover will kick off the seminar series by giving an important overview of AI in the K–12 landscape, including developing both AI literacy and AI ethics. Shuchi will provide concrete examples and recently developed frameworks to give educators practical insights on the topic.

    Our second session will focus on a teacher professional development (PD) programme to support the introduction of AI in Upper Bavarian schools. Franz Jetzinger from the Technical University of Munich will summarise the PD programme and share how teachers implemented the topic in their classroom, including the difficulties they encountered.

    Again from Germany, Lukas Höper from Paderborn University, with Carsten Schulte will describe important research on data awareness and introduce a framework that is likely to be key for learning about data-driven technology. The pair will talk about the Data Awareness Framework and how it has been used to help learners explore, evaluate, and be empowered in looking at the role of data in everyday applications.  

    Our April seminar will see David Weintrop from the University of Maryland introduce, with his colleagues, a data science curriculum called API Can Code, aimed at high-school students. The group will highlight the strategies needed for integrating data science learning within students’ lived experiences and fostering authentic engagement.

    Later in the year, Jesús Moreno-Leon from the University of Seville will help us consider the  thorny but essential question of how we measure AI literacy. Jesús will present an assessment instrument that has been successfully implemented in several research studies involving thousands of primary and secondary education students across Spain, discussing both its strengths and limitations.

    What to expect from the seminars

    Our seminars are designed to be accessible to anyone interested in the latest research about AI education — whether you’re a teacher, educator, researcher, or simply curious. Each session begins with a presentation from our guest speaker about their latest research findings. We then move into small groups for a short discussion and exchange of ideas before coming back together for a Q&A session with the presenter. 

    An educator is helping two young learners with a coding task.

    Attendees of our 2024 series told us that they valued that the talks “explore a relevant topic in an informative way“, the “enthusiasm and inspiration”, and particularly the small-group discussions because they “are always filled with interesting and varied ideas and help to spark my own thoughts”. 

    The seminars usually take place on Zoom on the first Tuesday of each month at 17:00–18:30 GMT / 12:00–13:30 ET / 9:00–10:30 PT / 18:00–19:30 CET. 

    You can find out more about each seminar and the speakers on our upcoming seminar page. And if you are unable to attend one of our talks, you can watch them from our previous seminar page, where you will also find an archive of all of our previous seminars dating back to 2020.

    How to sign up

    To attend the seminars, please register here. You will receive an email with the link to join our next Zoom call. Once signed up, you will automatically be notified of upcoming seminars. You can unsubscribe from our seminar notifications at any time.

    We hope to see you at a seminar soon!

  • A new Plug and Make Kit challenge! A game of rhythm and creativity

    A new Plug and Make Kit challenge! A game of rhythm and creativity

    Reading Time: 3 minutes

    The Arduino Plug and Make Kit is all about unleashing creativity while simplifying the process of turning ideas into reality. It enables everyone to focus on the fun of creating with the power of the UNO R4 WiFi and a user-friendly, modular design – bypassing the complexities of traditional circuit building. 

    Case in point: the kit’s intuitive features inspired Loris Bottello to create a project that combines his passion for music with playful interaction. A project he kindly shared with us – and all of you! – with this great step-by-step guide on Project Hub.

    Meet Loris Bottello, Plug and Make Kit Star

    Bottello worked for years at Arduino as a Senior Product Designer, focusing on Arduino Cloud and Project Hub. An expert at creating user-friendly tools and platforms that empower makers, he was excited to participate in our role-reversing Make Tank – where colleagues from different teams joined efforts to put the Plug and Make Kit to the test. 

    It was during one of these in-house sessions that some experimentation with Modulino nodes led to Sync a Song. The concept of syncing music and lights came naturally to Bottello, who is also a singer and guitarist in a rock band.

    [youtube https://www.youtube.com/watch?v=nZoxANVnjuY?feature=oembed&w=500&h=281]

    Sync a Song

    Sync a Song is a game for one or two players, reminiscent of vintage reel-to-reel tape recorders: the challenge is to spin two reels at the same speed. When in perfect sync, you’ll see LEDs light up green and hear a song as your reward. Want a new tune? Simply press the buttons on Modulino Buttons to switch tracks!

    While you’ll need two Plug and Make Kits to complete this project, assembly is straightforward: just use two Modulino bases connected by Qwiic cables – you can even top them with 3D-printed reels for an authentic retro look. 

    And have fun customizing your own version! It’s easy to add a favorite song or tweak the visuals to create your own interactive, creative experience, mixing playful nostalgia and modern tech.

    Less (complexity) is more (fun)

    For Bottello, the Plug and Make Kit’s biggest strength lies in its simplicity and flexibility. “In the past, I spent a lot of time figuring out circuits and debugging hardware. With the kit, I can dive straight into coding and focus on building an interesting experience,” he explains. By eliminating the need for breadboards, wires, and resistors, the kit allows creators to dedicate more time to refining their ideas and exploring new possibilities.

    “The Plug and Make Kit is perfect for experimenting and learning by creating a variety of projects without overthinking the technical setup. It’s a true enabler of creativity.”

    So, grab your Plug and Make Kit and check out the full tutorial to recreate Sync a Song: you’ll be bringing your own ideas to life in no time! 

    Don’t forget to share your creations with us on Project Hub or email creators@arduino.cc to get in touch: we can’t wait to see what you build.

  • This unique wall sconce welcomes you home with warm light

    This unique wall sconce welcomes you home with warm light

    Reading Time: 2 minutes

    Have you ever walked through your front door after a long day of work and realized that your home just isn’t as inviting as it seems like it should be? While it may not work miracles, some nice and welcoming lighting can make a big difference. That’s why Lauren Palazzi made this unique wall sconce called Acceptus that automatically turns on when it detects your arrival.

    Smart features aside, this is an intriguing design with a shape that generates interest all on its own. The wood base, carved in two pieces with a CNC router, has a profile that feels organic. Even before the light comes on, it projects warmth. The LED lighting on the internal perimeter enhances that effect with a soothing glow. Laser-cut acrylic “cover” panels on the front give the sconce a modern art vibe that is sure to appeal to many.

    The key smart feature of Acceptus is the presence detection, which lets it turn on the LED lighting when it senses your arrival. That works using an Arduino Nano ESP32 board that monitors an area, such as the entry way by the front door, through a PIR (passive infrared) motion sensor. That’s the same kind of sensor used for security floodlights and the technology is very reliable. When the Arduino “sees” movement through that PIR sensor, it uses a transistor to connect power to the LED strip.

    Palazzi recommends mounting Acceptus next to the door frame, opposite the hinges. That way, the movement of the door will activate the light. If you want to build your own Acceptus, Palazzi was kind enough to upload all of the necessary files to Instructables.

  • This frighteningly realistic animatronic head features expressive silicone skin

    This frighteningly realistic animatronic head features expressive silicone skin

    Reading Time: 2 minutes

    The human face is remarkably complex, with 43 different muscles contorting the skin in all kinds of ways. Some of that is utilitarian — your jaw muscles are good for chewing, after all. But a lot of it seems to be the result of evolution giving us fantastic non-verbal communication abilities. That isn’t an easy thing to replicate by artificial means, but Will Cogley managed to make this silicone-skinned animatronic head that is frighteningly realistic.

    Most people, when seeing this animatronic head, will feel something between unease and outright disgust or terror. Cogley purposefully exaggerated the movements and proportions to give the head a more cartoonish appearance in an attempt to navigate around the uncanny valley, but it still looks a bit too human to be comfortable. 

    That is largely the result of the realistic silicone skin that Cogley molded and then attached onto the internal skeleton (skull?) frame using magnets. That attachment method is pretty similar to the way our own people skin attaches to our muscles and tendons, and it produces expressions that are quite human.

    The internal skeleton was 3D-printed and actuated by a plethora of small servo motors. Cogley designed a custom shield PCB for an Arduino Mega 2560 to control the servos. He hasn’t yet programmed it beyond a handful of basic movements and facial expressions, but he’s set it up so that there is a great deal of potential for future programmatic upgrades.

    [youtube https://www.youtube.com/watch?v=yWrldOS6xBw?feature=oembed&w=500&h=281]

    Going forward, Cogley wants to experiment with some other molding techniques and so we may see an even more realistic version soon.
