Signal Input/Output
Use a rotary encoder with quadrature pulses as an input device.
This library decodes the signals from a rotary encoder and translates them into a counter position. The library comes with some samples that show how to use the library with and without interrupts.

This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
