If you want rotary encoders and OLED ... dial’s pulses with an Arduino Nano and using a Python script to monitor the serial connection and translate the pulses to volume control.

As for the volume knob itself, it’s not a real analog pot, instead it’s using a rotary encoder with a center push button. The way it works is that the Arduino reads the encoder, and figures ...

I have to thank one author of a rotary encoder decoder (Ben Buxton). While his code seemed overly complex to my untutored eye, for example creating a new data type, it did show Arduino-novice me ...

Now that your rotary encoder hardware is up and running it’s time to tell your Arduino what to do with the encoder signals. There are the two basic ways to read a microcontroller’s digital input. With ...
