The little ULN2003 board that partners the 28BYJ-48 stepper: a white JST socket for the motor's five-wire plug, IN1-IN4 pins to your Arduino, four LEDs that light in turn so you can watch the coils firing, and a jumper to cut motor power without unplugging anything. The Darlington array handles 500mA per channel and wants its own 5V supply rather than the Arduino's regulator. Paired with a 28BYJ-48 and its 64:1 gearbox that gives 2048 steps per revolution - real positioning for pocket money.
Key features
- Drives the 28BYJ-48 and similar 5-wire unipolar steppers
- ULN2003 Darlington array, 500 mA per channel
- Four control pins, IN1-IN4, no library needed
- An LED per coil shows the stepping sequence
- JST socket matches the 28BYJ-48 plug
- Jumper cuts motor power for safe testing
