Rotary encoder pinout and wiring. Most RTs also has built in ‘push-on’ momentary switch, usually one side has 3-pins (two coding pins and one common/ground pin) and the other side has 2-pins (N/O ...

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.

It is amazing how many Arduino programmes for decoding rotary encoders start with something like: "I looked at all the available rotary encoder sketches. About Us; Contact Us; ... // Encoder 1 pin A ...
