In this project tutorial we are going to Control the Speed of Dc Motor Wirelessly Using IR or TV Remote Control. This circuit can control the DC motor speed in 5 different levels and any IR remote ...

Isolating problems in the control circuitIn Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic ...

In this tutorial, a simple motor driver, dual-channel H-bridge is used. It allows control of bi-directional and variable speed of up to two motors. Note that this covers a specific type of motor ...
