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 a microcontroller’s digital input. With ...

Fully elaborated circuit diagrams, done in the same style, of course. “ABC: Basic Connections” started out life as a compendium of frequently used sub-circuits in Arduino projects. But you can ...

I have to thank one author of a rotary encoder decoder (Ben Buxton). While his code seemed overly complex to my untutored eye, for example creating a new data type, it did show Arduino-novice me two ...
