Italian artist, designer, and inventor Bruno Munari is usually quoted as saying “If I pay attention, I overlook; if I see, I bear in mind; if I do, I perceive.” We couldn’t agree extra, and that is likely one of the the reason why we imagine within the energy of our Challenge Hub to assist everybody really study, develop, and innovate. The tutorials our neighborhood shares usually are not solely “recipes” you may replicate, however alternatives to go deeper and take a look at completely different abilities in actual life. Don’t imagine us? Take a look at this month’s high three picks!
Perplexed about the easiest way to securely multiplex a seven-digit LED show? Adrian Smith’s write-up gives an exquisite deep dive into electronics design greatest practices, suggesting shift registers as an alternative choice to immediately connecting show segments and digit commons to microcontroller pins. The instance, primarily based on an Arduino UNO Rev3, will spur you to mirror on the interrelations between price, complexity, and the essential must keep away from overloads.
Your favourite Arduino module – Portenta H7 or H8, GIGA R1 WiFi, or Nano ESP32 will work nice! – can inject a treasured dose of flexibility right into a field-programmable gate array (FPGA) to finish excessive duties. Discover out extra concerning the common structure and software program drivers that may assist you appropriately stability parts’ efficiency, velocity and prices: Dave Nardella’s Challenge Hub add shouldn’t be a lot a step-by-step tutorial, however a springboard for infinite concepts!
Biking is an eco-friendly and wholesome means of transferring across the metropolis! However site visitors might be chaotic and security ought to all the time be the precedence: that’s why we love Luis Castillo’s concept so as to add route indicators to the again of a bicycle. Activated by way of buttons put in immediately on the handlebars, two LED arrows not solely talk clearly if you end up prepared to show left or proper, but additionally enhance visibility and, after all, are an incredible excuse to attempt 3D printing, laser chopping, wiring, programming, and extra!
These three Challenge Hub entries have been chosen for a $100, $300, and $500 present card to spend on the Arduino Retailer, based on the phrases and circumstances of the Challenge Hub Competitors we ran in 2023. Thanks all, in your contributions to open-source sources!
