Easy implement rotary encoder to your application using microcontroller like ESP32, STM32 and Atmega AVR - kr4fty/ai-rotary-encoder ...

There are already many rotary encoder libraries for Arduino, but I had trouble finding one that met my requirements. I did find a couple that were beautifully crafted, but wouldn't work on the ESP32.

There’s a lot to like about this little remote, which is based upon a LilyGo TTGO ESP32 board with on-board display. The circuitry is basically that and a rotary encoder plus a tiny LiPo battery.

Now suppose your latest self-quarantine project needs a rotary shaft encoder. Not having one, what do you do? If you are [Tech Build] you go all MacGyver on an old printer and pull out a stepper ...
