Uln2003 Stepper Motor Driver Circuit Arduino

The connections are also given in the table below.

Uln2003 stepper motor driver circuit arduino.

Usually the 28byj 48 stepper motor comes with a 5 pin connector that will fit to the uln2003 driver board. Arduino uln2003a based stepper driver board. We have used the 28byj 48 stepper motor and the uln2003 driver module. The 28ybj 48 stepper motor operates on 5vdc and has built in reduction gears.

Connect the uln2003 driver ln1 ln2 ln3 ln4 to the arduino digital pins 8 9 10 and 11 respectively. Now that we know everything about the motor we can begin hooking it up to our arduino. To energise the four coils of the stepper motor we are using the digital pins 8 9 10 and 11.

Connecting the uln2003 driver board to the arduino. The 28byj 48 stepper motor can draw up to 240 ma considerably more than what an arduino can deliver through any of its ports. Note that it is possible to directly power the stepper motor from the arduino. Unlike unipolar steppers bipolar steppers have no common center connection.

The circuit diagram for the arduino stepper motor control project is shown above. Arduino stepper motor control circuit diagram and explanation. Connecting the 28byj 48 stepper motor to the uln2003 driver board. There are numerous ways to create a driver starting with a simple transistor for each of the coils.

28byj 48 28byj 48 unipolar stepper motor. It has good torque for its size but has relatively slow motion. Start by connecting the power supply up to the uln2003 driver. Wiring connecting 28byj 48 stepper motor and uln2003 driver board to arduino uno.

Click here to buy 5v 4 phase 5 wire stepper motor and stepper motor driver board uln2003 for arduino. Uln2003 stepper motor driver. 5 6 or 8 wire stepper motor i e. Uln2003a can also be used to drive different motors e g.

The bipolar stepper motor usually has four wires coming out of it. Wiring 28byj 48 stepper motor and uln2003 driver to arduino. So you will need some sort of a driver to safely control the stepper motor. The wiring diagram schematic below shows you how to connect the uln2003 driver board to the 28byj 48 stepper motor and the arduino.
