Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

Featured in this project is the control of a stepper motor with its speed, direction, and step size by sending some signals through the parallel port. The project provides better understanding and ...

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...
