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

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.

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.

DIY enthusiast zine Make offers instructions and a video tutorial on how to construct the rotary knob controller using a PS/2 or USB mouse with scroll wheel.
