This article describes the Simple Stepper Motor Controller CIRCUIT (SL100). The principle is very simple, very practical. The circuit components can help you understand better grasp this principle. For example, in this circuit, you can go to find and buy these components:SL100. Meanwhile, we also welcome you to join us to explore these circuit theory, and be grateful for you to provide your comments and resources.

Stepper motor controller is needed to run a stepper motor, since a stepper motor cannot work by just connecting it to a power supply. ?To program a stepper motor to make a complex movement, we usually need a micro controller. Fortunatelly, for a simple movement like just rotating eith a constant speed, we can use avery simple circuit as described here. Here is the schematic diagram of the controller circuit:

This stepper motor controller circuit still need an external input. If we look at the table, the input pattern is similar to a 2 bits binary counter. ?If you have an up-down binary counter, then you get a forward-reverse control for your stepper motor.
