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

RPM Monitor that uses a Optical Rotary Incremental Encoder to monitor the RPM.

A precise and user-friendly Arduino project for real-time monitoring of conveyor belt speeds. Utilizing a rotary encoder and an LCD display, this tool measures RPM and calculates belt speed in meters per second and meters per minute, enhancing industrial efficiency and safety.

A project to build and interface a precision digital protractor to a facting machine giving a resolution of 1/40 degree. The system employs a US Digital E6 Optical Encoder, Arduino Nano and Waveshare 1.5" colour OLED display.
