Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

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 ...

It is amazing how many Arduino programmes for decoding rotary encoders start with something like: "I looked at all the available rotary encoder sketches ...

Spinning the rotary encoder cycles through a menu of programs on the 16×2 LCD, and the key map just updates automatically for the chosen program.

Hooked to an Arduino, the motor made a workable encoder, later improved by sending each phase through a comparator and using digital inputs rather than using the Nano’s ADCs.

“Roendi (Rotary Encoder with Display) features a STM32L433 MCU, 1.28″ TFT round display and a Alps Alpine 15Pulses/30Detent encoder. It can be programed either using ST-LINK/V2 or Arduino IDE ...
