This project demonstrates how to measure the RPM (Revolutions Per Minute) of a rotating object using an optical encoder with an Arduino. The code counts pulses generated by the encoder and calculates ...

This Arduino sketch is used to control 2 DC motors and 2 optical encoders from printer head frame by step/ direction signals.

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...
