8051 Micro + ULN2003 Stepper Motor Control

Posted September 3, 2012 by Chris

“This project is an extension to two-phase Unipolar Stepper motor interfacing with AT89C51. In the previous project, transistor switches were used to interface the stepper motor with the microcontroller. Here the transistors have been replaced by using a ULN2003 IC to drive the stepper with 8051 microcontroller.”
