Connect the uln2003 driver ln1 ln2 ln3 ln4 to the arduino digital pins 8 9 10 and 11 respectively.
Uln2003 stepper motor driver circuit arduino.
There are numerous ways to create a driver starting with a simple transistor for each of the coils.
It has good torque for its size but has relatively slow motion.
To energise the four coils of the stepper motor we are using the digital pins 8 9 10 and 11.
5 6 or 8 wire stepper motor i e.

Connecting the 28byj 48 stepper motor to the uln2003 driver board.
Arduino stepper motor control circuit diagram and explanation.
Start by connecting the power supply up to the uln2003 driver.
Unlike unipolar steppers bipolar steppers have no common center connection.
Arduino uln2003a based stepper driver board.
So you will need some sort of a driver to safely control the stepper motor.
The bipolar stepper motor usually has four wires coming out of it.
Uln2003a can also be used to drive different motors e g.
The 28ybj 48 stepper motor operates on 5vdc and has built in reduction gears.
