28BYJ-48 Stepper Motor with ULN2003 & Arduino | Full Step vs Half Step

In this video, we will learn how to interface the 28BYJ-48 stepper motor with the ULN2003 driver module using Arduino. We will also explore how to control two stepper motors simultaneously, where one motor operates in full-step mode and the other in half-step mode using the AccelStepper library.

The 28BYJ-48 is a popular 5V stepper motor with an internal gearbox that provides high torque and precise control. In this tutorial, we explain its working in detail, including its gear ratio (64:1), step angle, and why it requires 2048 steps per revolution in full-step mode and 4096 steps in half-step mode.

We also cover the ULN2003 driver module, which uses a Darlington transistor array to safely drive the motor coils and includes built-in flyback diodes to protect the circuit from voltage spikes.

What You Will Learn:

✅ How 28BYJ-48 stepper motor works
✅ ULN2003 driver module explained
✅ Full-step vs half-step operation
✅ Step sequence for stepper motor control
✅ Controlling multiple stepper motors with Arduino
✅ Using the AccelStepper library for smooth motion control

By the end of this video, you will fully understand how stepper motors work and how to control them efficiently using Arduino. You’ll also be able to implement both full-step and half-step modes in real projects.
