h bridge circuit


Posted on Feb 7, 2014

An H bridge is a kind of circuit you use to control the direction (and sometimes speed) of an electric motor, using only a single polarity voltage (you need to reverse the way current flows in order to reverse the way the motor rolls). You have 4 transistors, wired as ON OFF switches. Two signal lines allow you to run the motor in one direction, w

hen reversed, the motor runs in the other direction. It`s very straightforward to use and build, but be careful to use only small motors, as the currents drawn from the bigger types can burn your components.
