12 V Bidirectional Motor Control

Published in issue 367, July/August 2007

This simple circuit drives DC motors with a maximum current of 1 A and can be built with readily available components. The output voltage is adjustable between 0 and 14 V and the polarity can be changed so that not only motor speed but also rotation direction can be adjusted by turning a knob. The circuit is also ideal as a controller for a DC model railway or small low-voltage hobby tool.
