Control stepper motor through your computer's parallel port.

Buildan easy stepper motor driver that will allow you to precisely control aunipolar stepper motor through your computer's parallel port.

The project comes with a program that has easy to use graphicalinterface, allows you to control the motor speed, direction inreal-time and it also allows you to use and learn about differentstepping methods, such as single stepping, high torque stepping andhalf stepping modes.

Stepper motor controller also displays an animation that helps youvisualize the current as it flows through individual coils. It is awonderful tool to learn how stepper motors work.
