I needed a rotary encoder — I pulled a cheap one out of one of those “49 boards for Arduino” kits you see ... but it also depends on the edge you measure and how you connect everything.

Leine & Linde’s XHI 801 and XHI 803 rotary encoders ... addition to the standard encoder outputs. This allows the standard output to interface with a local control system, and the optical channel can ...

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 ...

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 ...

This 12-bit resolution magnetic rotary encoder detects rotational angle, vertical distance and magnetic tilt. The device can detect vertical distances over several millimeters, making it suitable for ...
