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 ...

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.

The encoder we had was on a little PCB that you get when you buy one of those Chinese Arduino 37 sensor kits. (By the way, if you are looking for documentation on those kinds of boards, look here ...

Arduino’s GND rail is common to the rotary encoder’s common pin (C) and the cathode of LED 3, while the 5V rail is used to pull-up the data pins (A &B). Arduino’s D9 pin controls LED3. During power on ...

It comes in the form of a PCB with four footprints that accept one of the most common rotary encoder forms (Bournes PEC11 horizontal style), allowing the user to pick devices with the appropriate step ...
