This project shows how to drive and control a Stepper Motor using a USB Interface. It is controlled via USB interface where small software running on the computer can control the stepping sequence of the stepper motor connected over USB. The stepping sequence and delay between the stepping sequence can be controlled easily with software. USB Stepper Motor Driver project is inexpensively easy to make and can be easily modified to run various types of stepper motor. The project is posted with necessary schematic, description and project files.
