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 potentiometers, but rotate all ...

This project is a DIY simple optical rotary encoder with 180 points per rotation and bi directional detection that you can make at home with a 3D printer. This Arduino Rotary Encoder is intended to ...

Rotary encoder decode for Arduino It is amazing how many Arduino programmes for decoding rotary encoders start with something like: “I looked at all the available rotary encoder sketches and none of ...
