Uln2003 Stepper Motor Driver Circuit Arduino

Unlike unipolar steppers bipolar steppers have no common center connection.

Uln2003 stepper motor driver circuit arduino.

The 28ybj 48 stepper motor operates on 5vdc and has built in reduction gears. Connecting the 28byj 48 stepper motor to the uln2003 driver board. They have two independent sets of coils instead. 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. So you will need some sort of a driver to safely control the stepper motor.

Connect the uln2003 driver ln1 ln2 ln3 ln4 to the arduino digital pins 8 9 10 and 11 respectively. Uln2003 stepper motor driver. To energise the four coils of the stepper motor we are using the digital pins 8 9 10 and 11. There are numerous ways to create a driver starting with a simple transistor for each of the coils.

Uln2003a can also be used to drive different motors e g. Some of the other applications of uln2003 include logic buffers lamp drivers line drivers led display motor driver circuits etc. Connecting the uln2003 driver board to the arduino. It has good torque for its size but has relatively slow motion.

Dc motors or stepper motors with microcontrollers like arduino pic microcontroller or 8051 microcontroller etc. The circuit diagram for the arduino stepper motor control project is shown above. The connections are also given in the table below. Start by connecting the power supply up to the uln2003 driver.

Arduino uln2003a based stepper driver board. Note that it is possible to directly power the stepper motor from the arduino. Now that we know everything about the motor we can begin hooking it up to our 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.

Wiring 28byj 48 stepper motor and uln2003 driver to arduino. We have used the 28byj 48 stepper motor and the uln2003 driver module. The wiring diagram schematic below shows you how to connect the uln2003 driver board to the 28byj 48 stepper motor and the arduino. Wiring connecting 28byj 48 stepper motor and uln2003 driver board to arduino uno.
