6. Interfacing Stepper Motor with PIC Microcontroller

Stepper Motor is an exceptionally planned engine which turns in steps. Speed of stepper engine relies upon the pace of electrical sign applied to it. Various examples can control stepper engine's heading and pivot type. Principally 2 kinds of stepper engines are accessible, Unipolar along with Bipolar. Unipolar is simpler to work, control and furthermore simpler to get. Here in this instructional exercise we are interfacing Stepper Motor with PIC Microcontroller PIC16F877A.

We are utilizing 28BYJ-48 stepper engine for this undertaking which is modest and effectively accessible. It is 5V DC unipolar stepper engine. We are additionally utilizing a Module accessible with this engine which comprise ULN2003 Stepper Motor Driver IC. ULN2003 is a Darlington pair exhibit, which is valuable to drive this engine, since PIC microcontroller couldn't give enough current to drive. ULN2003A is skilled to drive 500mA of burden with 600mA of pinnacle current.
