Encoded Stepper Motor Controller

Encoded Stepper Motor Controller

This circuit illustrates the complex operations that can go on inside modern dedicated integrated circuits. The circuit uses a bi-directional digital rotary encoder to step a unipolar stepper motor. One click on the encoder steps the stepper motor one step (or half step). This discrete motion can then be geared up or down to suit your particular purpose. You need to supply the six wire unipolar stepper motor.  Will not work with 4 wire, bipolar steppers.
