Uln2003 Stepper Motor Driver Circuit Arduino

The connections are also given in the table below.

Uln2003 stepper motor driver circuit arduino.

Wiring connecting 28byj 48 stepper motor and uln2003 driver board to arduino uno. The 28ybj 48 stepper motor operates on 5vdc and has built in reduction gears. The wiring diagram schematic below shows you how to connect the uln2003 driver board to the 28byj 48 stepper motor and the arduino. There are numerous ways to create a driver starting with a simple transistor for each of the coils.

Wiring 28byj 48 stepper motor and uln2003 driver to arduino. Arduino uln2003a based stepper driver board. Arduino stepper motor control circuit diagram and explanation. Note that it is possible to directly power the stepper motor from the arduino.

To energise the four coils of the stepper motor we are using the digital pins 8 9 10 and 11. Start by connecting the power supply up to the uln2003 driver. The 28byj 48 stepper motor can draw up to 240 ma considerably more than what an arduino can deliver through any of its ports. Click here to buy 5v 4 phase 5 wire stepper motor and stepper motor driver board uln2003 for arduino.

Usually the 28byj 48 stepper motor comes with a 5 pin connector that will fit to the uln2003 driver board. Connect the uln2003 driver ln1 ln2 ln3 ln4 to the arduino digital pins 8 9 10 and 11 respectively. Uln2003 stepper motor driver. It has good torque for its size but has relatively slow motion.

We have used the 28byj 48 stepper motor and the uln2003 driver module. The bipolar stepper motor usually has four wires coming out of it. 5 6 or 8 wire stepper motor i e. So you will need some sort of a driver to safely control the stepper motor.

Connecting the 28byj 48 stepper motor to the uln2003 driver board. Dc motors or stepper motors with microcontrollers like arduino pic microcontroller or 8051 microcontroller etc. 28byj 48 28byj 48 unipolar stepper motor. Some of the other applications of uln2003 include logic buffers lamp drivers line drivers led display motor driver circuits etc.

Now that we know everything about the motor we can begin hooking it up to our arduino. Connecting the uln2003 driver board to the arduino. Unlike unipolar steppers bipolar steppers have no common center connection. They have two independent sets of coils instead.
