Stepper motor controller
This project allows you to control the speed, direc-tion, and step size of a
unipolar four-phase step-per motor. The controller is capable of handling motor
winding currents of up to 1.25 amps per phase and it operates from a single
supply voltage of 6-30 volts DC.
If you’re interested in robotics, motion control, or just want
to learn about stepper motors, then
you should try building this versatile stepper motor controller.
