Spinning the rotary encoder cycles through a menu of programs on the 16×2 LCD, ... At the heart of this build is an Arduino Pro Micro and 20 of the loudest key switches ever made — Cherry MX blues.

This lovely input has an Arduino Pro Micro for a brain, and Gateron browns for brawn. That knob there is a rotary encoder, not a potentiometer, because endless volume knob twiddling is just so ...

Rotary encoder vs potentiometer. A rotary encoder is a wonderful digital alternative to the old analog potentiometers. Rotary encoders are useful as rotation sensors (or selectors) and look similar to ...
