Awhile ago I bought Digistump’s ATTiny85 out of curiosity and because it didn’t need anything and could be plugged directly into USB. Made LED blink then made it output square wave siren.
Then Pi Pico got released so I tried that but it lacked, convenient at that time, Arduino IDE support, so didn’t really stick…yet.
Then I bought Nano clone that I thought was Arduino. About at the same time I discovered Visual Micro for Visual Studio and now I only use Arduino IDE for Serial Monitor/Plotter.
Then I started buying genuine Arduino boards, Nano Every (many times), DUE, MKR ZERO, Nano connect. I made 2 Bluetooth speakers small and big. Small runs on Nano Every. Big on MKR ZERO, in both projects I used every last pin available. This was challenging and I enjoyed solving many problems.
So what about you? I am genuinely interested what other people are doing with their Arduinos.
Oh and Happy New 2022!
