  • Part 10: Stepper Motors

    In this lesson we learn how to use mini stepper motor 28BYJ-48 for our project. I am presenting with 8 projects so you can use it in almost any applicaiton. In the video, I have explained the code, shown full wiring diagram and how connect the wires, push buttons and bread board.

    Projects

    In Project 1 We simply control the motor to run and stop. The direction of rotation is set in the code as explained in the video.
