Uln2003 Stepper Motor Driver Circuit Arduino

Connecting the 28byj 48 stepper motor to the uln2003 driver board.

Uln2003 stepper motor driver circuit arduino. Uln2003a can also be used to drive different motors e g. Arduino uln2003a based stepper driver board. Uln2003 stepper motor driver. Click here to buy 5v 4 phase 5 wire stepper motor and stepper motor driver board uln2003 for arduino.

So you will need some sort of a driver to safely control the stepper motor. 28byj 48 28byj 48 unipolar stepper motor. Wiring connecting 28byj 48 stepper motor and uln2003 driver board to arduino uno. Initialize the stepper library on pins 8 through 11 void setup.

The connections are also given in the table below. Start by connecting the power supply up to the uln2003 driver. Wiring 28byj 48 stepper motor and uln2003 driver to arduino. Dc motors or stepper motors with microcontrollers like arduino pic microcontroller or 8051 microcontroller etc.

Include stepper h call stepper control const int stepsperrevolution 2048. We have used the 28byj 48 stepper motor and the uln2003 driver module. The circuit diagram for the arduino stepper motor control project is shown above. To energise the four coils of the stepper motor we are using the digital pins 8 9 10 and 11.

The bipolar stepper motor usually has four wires coming out of it. They have two independent sets of coils instead. The wiring diagram schematic below shows you how to connect the uln2003 driver board to the 28byj 48 stepper motor and 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.

Some of the other applications of uln2003 include logic buffers lamp drivers line drivers led display motor driver circuits etc. It has good torque for its size but has relatively slow motion. Number of steps per revolution stepper mystepper stepsperrevolution 8 10 9 11. Note that it is possible to directly power the stepper motor from the arduino.

Unlike unipolar steppers bipolar steppers have no common center connection. Now that we know everything about the motor we can begin hooking it up to our arduino. Usually the 28byj 48 stepper motor comes with a 5 pin connector that will fit to the uln2003 driver board.

The 28ybj 48 stepper motor operates on 5vdc and has built in reduction gears. 5 6 or 8 wire stepper motor i e. Connecting the uln2003 driver board to the arduino. There are numerous ways to create a driver starting with a simple transistor for each of the coils.
