CircuitPython [0] is "the easiest way to program microcontrollers". If you use Arduino or know a little bit of Python, consider joining this mini workshop [1].

Bring a laptop with USB, any OS. Get from blink to IoT in ~1 hour. Everything is open source, of course! We'll provide 10 hardware kits. 2 or 3 people can share a kit :)

Deutsch ou Français? Both is fine, we can help!
