H-Bridge Motor Controller

Many of us will consider this stuff basic; those who are trying to expand from building only things the arduino board can handle to bigger more expansive and powerful projects will find this quite helpful.

This tutorial is very in depth, not only going through the construction of the basic circuit but also showing you how to make your own PCB that can control a DC motor with a digital input. The H-bridge is a true concept for DC motor control. It allows you to move motors forward, backward and with varying speeds through PWM.

When it comes to constructing an H-bridge for DC motor control, you need to understand how the H-bridge itself works and what the different types of power transistors available and when to use. The next step is to assemble all of the parts for the 10A H-bridge. This means first you have to drill out the holes in the PCB and then solder the parts in. The mechanical push buttons will test the forward and reverse directions to make sure that the h-bridge works correctly and a PWM input to the H-bridge to show how adding a microcontroller allows you to vary speed.
