Uln2003 Stepper Motor Driver Circuit Arduino

Some of the other applications of uln2003 include logic buffers lamp drivers line drivers led display motor driver circuits etc.

Uln2003 stepper motor driver circuit arduino.

We have used the 28byj 48 stepper motor and the uln2003 driver module. So you will need some sort of a driver to safely control the stepper motor. Uln2003 stepper motor driver. Dc motors or stepper motors with microcontrollers like arduino pic microcontroller or 8051 microcontroller etc.

Wiring connecting 28byj 48 stepper motor and uln2003 driver board to arduino uno. Now that we know everything about the motor we can begin hooking it up to our arduino. Wiring 28byj 48 stepper motor and uln2003 driver to arduino. The circuit diagram for the arduino stepper motor control project is shown above.

Arduino uln2003a based stepper driver board. The wiring diagram schematic below shows you how to connect the uln2003 driver board to the 28byj 48 stepper motor and the arduino. Uln2003a can also be used to drive different motors e g. Usually the 28byj 48 stepper motor comes with a 5 pin connector that will fit to the uln2003 driver board.

5 6 or 8 wire stepper motor i e. The connections are also given in the table below. Start by connecting the power supply up to the uln2003 driver. Connecting the 28byj 48 stepper motor to the uln2003 driver board.

They have two independent sets of coils instead. Connect the uln2003 driver ln1 ln2 ln3 ln4 to the arduino digital pins 8 9 10 and 11 respectively. It has good torque for its size but has relatively slow motion. There are numerous ways to create a driver starting with a simple transistor for each of the coils.

Unlike unipolar steppers bipolar steppers have no common center connection. 28byj 48 28byj 48 unipolar stepper motor. Note that it is possible to directly power the stepper motor from the arduino. The 28ybj 48 stepper motor operates on 5vdc and has built in reduction gears.

The bipolar stepper motor usually has four wires coming out of it. Arduino stepper motor control circuit diagram and explanation. The 28byj 48 stepper motor can draw up to 240 ma considerably more than what an arduino can deliver through any of its ports. To energise the four coils of the stepper motor we are using the digital pins 8 9 10 and 11.
