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 ...

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

Can be programmed with STM32CubeIDE 1.6.1 or Arduino IDE “Roendi (Rotary Encoder with Display) features a STM32L433 MCU, 1.28″ TFT round display and a Alps Alpine 15Pulses/30Detent encoder.

I needed a rotary encoder — I pulled a cheap one out of one of those “49 boards for Arduino” kits you see around. Not the finest encoder in the land, I’m sure, but it should do the job.
