FAQ: Common Questions Answered ❓
What microcontrollers work best with this motor?
Arduino Uno, Nano, and Mega are most commonly used with the ULN2003 + 28BYJ-48 combo.
Do I need an external power supply?
It’s recommended to use a separate 5V power source if you’re driving multiple motors to avoid brownouts.
Is this motor bipolar or unipolar?
The 28BYJ-48 is a unipolar stepper motor with 5 wires.
Can I reverse the motor direction?
Yes! Just change the stepping sequence in your code.
How do I connect it to Arduino?
Use 4 digital pins from Arduino to the IN1~IN4 pins on the ULN2003 driver board.
Is this motor suitable for continuous rotation?
Not ideal. It’s designed for precise step movement, not high-speed continuous motion.
