Italian artist, designer, and inventor Bruno Munari is often quoted as saying “If I listen, I forget; if I see, I remember; if I do, I understand.” We couldn’t agree more, and that is one of the reasons why we believe in the power of our Project Hub to help everyone truly learn, grow, and innovate. The tutorials our community shares are not only “recipes” you can replicate, but opportunities to go deeper and test different skills in real life. Don’t believe us? Check out this month’s top three picks!
3. Master multiplexing
Perplexed about the best way to safely multiplex a seven-digit LED display? Adrian Smith’s write-up offers a wonderful deep dive into electronics design best practices, suggesting shift registers as an alternative to directly connecting display segments and digit commons to microcontroller pins. The example, based on an Arduino UNO Rev3, will spur you to reflect on the interrelations between cost, complexity, and the crucial need to avoid overloads.
2. Combine Arduino with FPGAs
Your favorite Arduino module – Portenta H7 or H8, GIGA R1 WiFi, or Nano ESP32 will work great! – can inject a precious dose of flexibility into a field-programmable gate array (FPGA) to complete extreme tasks. Find out more about the general architecture and software drivers that can help you appropriately balance components’ performance, speed and costs: Dave Nardella’s Project Hub upload is not so much a step-by-step tutorial, but a springboard for infinite ideas!
1. Make biking safer at every turn
Biking is an eco-friendly and healthy way of moving around the city! But traffic can be chaotic and safety should always be the priority: that’s why we love Luis Castillo’s idea to add direction indicators to the back of a bicycle. Activated via buttons installed directly on the handlebars, two LED arrows not only communicate clearly when you are ready to turn left or right, but also increase visibility and, of course, are a great excuse to try 3D printing, laser cutting, wiring, programming, and more!
These three Project Hub entries were selected for a $100, $300, and $500 gift card to spend on the Arduino Store, according to the terms and conditions of the Project Hub Competition we ran in 2023. Thank you all, for your contributions to open-source resources!
