    This system enables users to create room-sized interactive surfaces with spray paint

    Arduino Team — April 11th, 2020

    If you’ve ever thought of adding a user interface to an everyday surface — like a concrete wall, or even a sofa — MIT CSAIL’s SprayableTech system presents a variety of interesting possibilities. 

    Input elements, such as buttons and sliders, are airbrushed onto a surface like graffiti with a single layer of conductive ink, while electroluminescent displays can be formed by the application of multiple layers with different properties. Spray paint stencils for these interfaces are created with the help of a toolkit integrated into Blender. 

    An Arduino Uno is used to control this interactive surface, along with a custom Graffiti Shield. This allows it to handle six inputs and power for two electroluminescent displays.

    More details on the project can be found here.

    We present Sprayable User Interfaces: room-sized interactive surfaces that contain sensor and display elements created by airbrushing functional inks. Since airbrushing is inherently mobile, designers can create large-scale user interfaces on complex 3D geometries where existing stationary fabrication methods fail.

    To enable Sprayable User Interfaces, we developed a novel design and fabrication pipeline that takes a desired user interface layout as input and automatically generates stencils for airbrushing the layout onto a physical surface. After fabricating stencils from cardboard or projecting stencils digitally, designers spray each layer with an airbrush, attach a microcontroller to the user interface, and the interface is ready to be used. 

    Our technical evaluation shows that Sprayable User Interfaces work on various geometries and surface materials, such as porous stone and rough wood. We demonstrate our system with several application examples including interactive smart home applications on a wall and a soft leather sofa, an interactive smart city application, and interactive architecture in public office spaces.

    Control a stepper motor using a laptop touchpad

    Arduino Team — April 10th, 2020

    While laptops eventually become past their prime, many of the underlying bits and pieces are still functional and could be reused. If you’re wondering what to do with an old touchpad, especially one with a Synaptics chip, then this stepper motor control project should provide some inspiration.

    Here the touchpad is read by an Arduino Leonardo using a PS/2 library, which translates these finger swipes into stepper signals via a driver board. 

    When the user scrolls forward or backward, the motor responds either with a nice natural acceleration/deceleration motion, or the ability to move to a certain set point with a tap.

    A mesmerizing magnetic clock for your wall

    Arduino Team — April 8th, 2020

    Magnets are amazing devices, and thanks to this project by “tomatoskins,” they can even be used to mysteriously tell time. His project uses magnets hidden behind a classic walnut veneer to rotate a pair of ball bearings around the unique clock face.

    While externally minimal, there’s a lot going on inside its wood surface. The clock is controlled by an Arduino Nano along with an RTC module for accurate timekeeping. A 28BYJ-48 stepper motor-driven, 3D-printed gear system guides magnet positions and Hall effect sensors are used for both the hour and minute hands. 

    Arduino code as well as mechanical design files are available in tomatoskins’ write-up.

    The Orb is a “rolly, tumbly, singy” synthesizer by Emily Velasco

    Arduino Team — April 7th, 2020

    Some years ago, Emily Velasco started exploring the idea of creating a musical instrument based on a pendulum. This didn’t work out exactly the way she’d planned, but after several iterations — and inspiration from a cat toy — the device eventually turned into a sort of wobbling egg-shaped instrument, which sings as it tilts and tumbles. 

    The Orb —  as seen and heard in the video below — is truly strange, reminiscent of a theremin morphed with a trendy bowl-shaped wooden speaker. 

    As it’s spun, the Orb produces a sort of warbling noise, and one can position it to vary the sound by hand if they so desire. Inside lies an Arduino Nano running the Mozzi audio synthesis library, along with an accelerometer and audio amplifier board.

    DIY collective control lever for a helicopter flight sim

    Arduino Team — April 3rd, 2020

    Kaleb Clark really enjoys flight simulators, but when attempting to fly a helicopter, a normal keyboard or even a joystick isn’t quite optimal for controlling its vertical movement. Real helicopters use a lever assembly called a collective to adjust downward thrust, and he decided to build his own with an Arduino Micro and GPIO expander.

    To read the main lever action, he’s using a gear and encoder setup, which allows him to lift and descent in a much more natural way than afforded normal computer controls. There’s also has a bunch of buttons attached that can be programmed for various actions as needed. 

    Game interface is taken care of by the Micro’s ATmega32U4 chip, giving it HID functionality as an auxiliary input device.

    Interfacing an old arcade cash reader with an Arduino

    Arduino Team — April 2nd, 2020

    After picking up a free arcade machine, YouTuber “Another Maker” has naturally been considering what to do with it. One of the more interesting components included is the 1/5/10/20 U.S. dollar bill acceptor, which he outlines in the video below.

    The cash reader is powered by a 12V supply, and “emulates” quarter inputs to the machine by sending multiple signals for each bill. Meaning, a dollar would be output as four quarters, five times that for a five dollar bill, and so on. This functionality is shown at the end of the clip on an Arduino Mega with an LCD keypad shield. The machine also has a 5V input, which can activated by an Arduino to make it flash LEDs and reject all bills when “business is closed.”

    [youtube https://www.youtube.com/watch?v=Ot7_iEwcphg?feature=oembed&w=500&h=281]

    The code that enables it to read the device can be found on GitHub. And in case you’re wondering what Another Maker ended up building…

    The ArduINA226 is an Arduino-based power monitor

    Arduino Team — April 2nd, 2020

    Giovanni Carrera has created a capable power monitor, dubbed the ArduINA226, using an Arduino Nano and an INA226 IC. 

    This chip measures the current and voltage, and calculates power, which is then read by the Arduino board and sent to an LCD display. The unit also features a micro SD card for storage and later analysis, letting you track stats such as energy consumption over time.

    Nearly any sort of Arduino board can be used for this setup, but the Nano was chosen as it makes things nice and compact and has an included USB adapter. The electronics are mounted on a PCB and housed in a professional-looking enclosure. 

    A full schematic for the ArduINA226 is available in Carrera’s project write-up, along with code if you’d like to make your own.

    The Wash-A-Lot-Bot is a DIY handwashing timer

    Arduino Team — March 29th, 2020

    With the current coronavirus situation, we’ve been encouraged to wash our hands regularly for 20 seconds – or approximately how long it takes you to hum “Happy Birthday” from beginning to end twice. That sounds easy enough, but do you really do this every time? What you need is some sort of automatic timer, perhaps with a gauge for easy visual reference. 

    As it just so happens, Gautam Bose and Lucas Ochoa built such a device with an Arduino Uno. The aptly named Wash-A-Lot-Bot detects a person’s hands via an ultrasonic sensor, then ticks a dial timer from 0 to 20 (or rather 20 to DONE!) using a micro servo. 

    This simple setup can be made with little more than scissors and tape, making it a great way to learn about Arduino and programming while you’re stuck indoors.

    To the Arduino community:

    Humanity is facing one of the most trying events in its history and as technologists, makers and designers we are asking ourselves how can we help. 

    How can we contribute to the efforts to save lives, to help our fellow human beings?

    All of us have been thinking about this and observing what is going on in the world.

    We have seen communities, including all of you, trying to design devices that would help hospitals cope with the lack of equipment; we’ve seen people firing up their imagination and their 3D printers in an effort to build something that could save even a single human life.

    Having noticed that a large number of these efforts are using Arduino technology we reached out to a number of these communities to offer our help, donate some hardware, provide engineering support, and do whatever we can considering that we are a small company.

    One thing that was striking to us is the large amount of duplication in the work people are doing. Many people are spending valuable time trying to overcome similar challenges in their design, rather than sharing their solution to the benefit of all and moving on to the next hurdle. Also, there are different teams with different strengths and skill sets that would be better working together than apart.

    We must do better, be more effective, work together, and merge efforts to solve these problems and reach our common goal quicker and more efficiently.

    Because of all of this, we want to invite as many of these projects as possible to an online gathering, to get people talking, to offer help on how to design and make hardware, how to think about the software, and how to scale manufacturing (we would like to share our knowledge in making tens of thousands of open source boards per week). Finally and most importantly, we must take guidance from medical professionals so that they can steer requirements and validate the designs so our efforts have the most positive impact. 

    Join us online on April 2nd to understand how we can work together to do better together, and together — let’s make COVID-19 history.

    — David Cuartielles and Massimo Banzi, Arduino co-founders (on behalf of Arduino)

    Combating COVID-19 Conference: A Collaborative Arduino Community Initiative will take place on April 2nd at 5pm CET.

    SASSIE helps prevent awkward gaps in conversation

    Arduino Team — March 24th, 2020

    Whether it’s with an old friend or new acquaintance, we’ve all had those awkward gaps in conversation. Do you speak next, or let the other person lead the discussion? If that’s not happening naturally, then SASSIE, or “System for Awkward Silence Solution and Interaction Enhancer,” is here to help.

    The cylindrical device detects audio feedback via a pair of microphones positioned near each person in a conversation. When a sufficient silence is detected, SASSIE pops a flag out and rotates to indicate who needs to talk. If that wasn’t enough of a hint, it also audibly tells that person to say something. 

    [youtube https://www.youtube.com/watch?v=Y9cKHJU2yeM?feature=oembed&w=500&h=281]

    SASSIE is powered by dual Arduino Uno boards, one of which takes care of the bulk of the control functions, while the other actuates the stepper to spin the top indicator.

    1,156 LEDs make up these dual acrylic light-up panels

    Arduino Team — March 24th, 2020

    What does one do with over 1,000 LEDs, white acrylic, and 288 IR sensors? If you’re Redditor “jordy_essen,” you create an interactive light panel.

    In one mode, the user pull a reflective tool across the sensors to draw a paths, with potentiometers implemented to select the color. It can also be set up to play a sort of whack-a-mole game, where one has to activate the sensor in the same area where it illuminates.

    For this amazing device, jordy_essen uses not one, or even two, but six Arduino Mega boards to drive the LEDs directly — in turn controlled by a webpage running on a Raspberry Pi. If that wasn’t enough hardware, an Uno is tasked with taking inputs from the color potentiometers. 

    It’s a brilliant project in any sense of the word!

    VersaTouch brings touch localization and force sensing to everyday surfaces

    Arduino Team — March 19th, 2020

    Researchers from the University of Auckland in New Zealand’s are exploring a new way to construct interactive touch surfaces using finger-mounted audio transducers. 

    VersaTouch — which works on everyday surfaces — uses one or more receivers to measure sound waves emanating from the wearer’s “augmented” fingers, allowing it to calculate their positions and/or movements. The plug-and-play system can also sense force based on a changing audio signature and track individual digits by alternating each one’s sonic outputs. 

    Importantly, VersaTouch can be configured without permanent modification to the newly interactive surface. The setup includes an Arduino Due to receive signals, a Teensy 3.6 to control the transducers, and a MacBook to process the data and calculate the touch positions with a Java program.

    More information on the project can be found in the team’s research paper, and you can see it demonstrated in the video below. 

    [youtube https://www.youtube.com/watch?v=B-U2Yurobfg?feature=oembed&w=500&h=281]

    VersaTouch is a portable, plug-and-play system that uses active acoustic sensing to track fine-grained touch locations as well as touch force of multiple fingers on everyday surfaces without having to permanently instrument them or do an extensive calibration. Our system is versatile in multiple aspects. First, with simple calibration, VersaTouch can be arranged in arbitrary layouts in order to fit into crowded surfaces while retaining its accuracy. Second, various modalities of touch input, such as distance and position, can be supported depending on the number of sensors used to suit the interaction scenario. Third, VersaTouch can sense multi-finger touch, touch force, as well as identify the touch source. Last, VersaTouch is capable of providing vibrotactile feedback to fingertips through the same actuators used for touch sensing.

    Designing a low-cost, open source ventilator with Arduino

    Arduino Team — March 17th, 2020

    Desperate times call for desperate measures, and while making your own medical equipment isn’t normally advisable, Johnny Lee’e project explores how to turn a CPAP machine into a ventilator.

    The idea is that since these machines are basically just blowers controlled by a brushless DC motor, an Arduino Nano equipped with an electonic speed controller could allow it to act as a one.

    Such a setup has been shown to provide more than enough pressure for a ventilator used on COVID-19 patients. This device has in no way been evaluated or approved for medical use, but it does provide a starting point for experimentation.

    You can find additional details on Lee’s GitHub page.

    Using an Arduino/CNC shield setup for ham radio control

    Arduino Team — March 16th, 2020

    Loop antennas for ham radios use heavy duty variable capacitors for tuning. Since such capacitors need to be physically turned for adjustment, radio enthusiast Jose B.O. made his own remote rig using an Arduino Uno and CNC shield.

    The CNC setup allows stepper motors to rotate through a range of angles for frequency selection, and three antennas can be controlled via separate Pololu A4988 driver modules. An optical encoder is used for control, along with buttons for preset frequencies, and a 16×2 I2C LCD display provides visual feedback. Microswitches are implemented to set the upper and lower bounds for the stepper motors.

    More info is available in the project’s write-up and the videos below show the system in action.

  • Thales, Telstra, Microsoft and Arduino deliver scalable trust for easy-to-deploy IoT Applications

    Thales, Telstra, Microsoft and Arduino deliver scalable trust for easy-to-deploy IoT Applications

    Reading Time: 2 minutes

    We’ve partnered with Thales, Telstra and Microsoft to pave the way for scalable security for connected IoT devices, by implementing a solution that enables trusted and secure end-to-end communication between device and cloud.

    The solution enables instant and standardized mutual authentication between a device and a cloud platform via cellular networks, while fully-complying with GSMA IoT SAFE security specifications.

    Within the IoT ecosystem, billions of devices collect, process and send data to the cloud, where a range of different IoT services are executed. To enable security, the IoT cloud service must have absolute trust in data received from connected devices. Equally, devices need to trust the cloud. This is only possible if the device and server are mutually authenticated. However, the IoT devices market is so fragmented — with a patchwork of different operating systems and chips being utilized — that security services scalability and duplication are very limited.

    That’s why Thales, Telstra, Microsoft[1]and Arduino[2] have decided to team up to work on a solution that addresses the challenge of securely and efficiently connecting IoT devices to clouds in the most simplified way and through cellular networks. The level of trust required is enabled by a sophisticated ‘security-by-design’ approach for any IoT devices based on field-proven and standardized SIM or eSIM technology.

    As a result, as soon as an IoT device is switched on, any SIM or eSIM featuring Thales’s IoT SAFE application is automatically and securely provisioned. Once the IoT device gets a proper Digital Certificate created and stored in the SIM/eSIM, then a trusted communication between the device and the server is permitted, in full respect of data integrity and confidentiality.  

    “We are very pleased to be part of the dream team composed by Thales, Telstra and Microsoft,” said Fabio Violante, Arduino CEO. “The development of this tool was a teamwork and a proof that Arduino is a great partner to create solid, reliable and easy to integrate hardware and software IoT solutions.“

    [1] Microsoft integrated the IoT SAFE solution with their Azure IoT Hub and also provided Azure Stream Analytics, Cosmos DB and Power BI services to quickly enable the development of an example end-to-end IoT application.

    [2] We developed a library (under an open source license) that implements the security mechanism of the GSMA IoT Safe standard on our MKR NB 1500 boards and provides a valid alternative to the usage of the crypto chip already present on the Arduino board. The project has been a great example of collaborations with companies operating in various IoT sectors through our brand new Arduino Pro division.
