DC Motor Controller
Approx construction cost US$14
Simply and inexpensively control low-voltage motors or lamps with this m onth’s “Top-Tenner” (beginners) project.
Inexpensive DC motors are often used by model-makers, not only for model locomotives and racing cars but in robots of all kinds. They may also be used for driving non-mobile models made from anything from cardboard to Meccano.
This project controls a small 6V DC motor, but can be used for 12V or higher-voltage DC motors as well. The circuit controls both the speed and the direction of the motor.
More details on this construction project can be found in the May 2001 issue of EPE Online, the world's first web-delivered electronics and computing hobbyist magazine.
