Adding Arduino to your rotary encoder. Now that your rotary encoder hardware is up and running it’s time to tell your Arduino what to do with the encoder signals. There are the two basic ways to read ...

CLK (A pin) - to any microcontroler intput pin with interrupt -> in this example pin 26 DT (B pin) - to any microcontroler intput pin with interrupt -> in this example pin 27 SW (button pin) - to any ...

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 library can calculate the RPM of the rotary encoder. It works best with a short update interval, by using a low update interval for the constructor for ESP32 or manually calling ...

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 ...
