AVR PC Stepper Motor Driver

AVR PC Stepper Motor Driver

This circuit allows you to control two unipolar stepper motors in full-step mode via your PC's RS232 serial port. You can use a terminal program (such as Hyperterminal) to control the stepper motors. One stepper motor can be driven at a time.
