This project presents an Arduino based speed monitoring system where the RPM (revolutions per minute) of a DC motor is continuously displayed on a smartphone using Bluetooth communication. The Arduino ...

Ive been working on making a DC treadmill motor run in a PID loop for a lathe application. Why? Well because its there I guess and I like to recycle. The treadmill motor I have is a permanent magnet ...

This project uses an Arduino to control the RPM of a motor using a PID controller. The RPM is measured using an optical sensor, and the motor speed is adjusted accordingly based on the setpoint value.
