As stated, the rotary encoder has 2 coding pins that are either HIGH (1) or LOW (0). If you treat the pins as binary, you can read them as 00, 01, 10, or 11 (sequence the encoder outputs while ...

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 ...

Taste The Code. How to Use Rotary Encoders and Interrupts With Your Arduino Projects. Posted: June 10, 2025 | Last updated: June 10, 2025. Hi, I'm Bill.

Rotary encoders are great devices. Monitoring just a few pins you can easily and quickly read in rotation and direction of a user input (as well as many other applications). But as with anything, t… ...

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.
