Lesson 107: Control Stepper motor 28BYJ-48 with ULN2003 for Arduino, 7 Projects

Please select other codes for this lecture from the links below.

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

Project 1: Running motor (this project)
Project 2: Controlling stepper motor from Serial Monitor
Project 3: Controlling stepper motor using push button STPB-1
Project 4: Controlling using push button STPB-2 keep pressing
Project 5: One Revolution using push button STPB-3
Project 6: Push button Any Angle and speed STPB-4
Project 7: ush multiple buttons to any angles STPB-5 angle, speed and direction
Project 8: Controlling stepper motor using potentiometer

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.
