This example uses the Stepper.h library, which should come pre-installed with the Arduino IDE.

You can upload the following example code to your Arduino using the Arduino IDE. Basic Arduino example code to control a 28BYJ-48 stepper motor

#PIN DIAGRAM ARDUINO MEGA 2560 DRIVER#

The jumper next to power connections on the driver board can be used to disconnect power to the stepper motor. Note that you also need to connect the GND of the Arduino to the – pin on the ULN2003 driver board.Īfter uploading the code you also need to power the Arduino, either with a USB type-B cable or via the 5.5 mm power jack. It should come with a female DC connector, so you can easily connect it to some (jumper) wires. I recommend to power the driver board/stepper motor with an external 5 V power supply, like this one. I also found that when powering the Arduino with USB power only, I would get inconsistent behavior and bad performance of the stepper motor. When the stepper motor draws too much current you can damage the Arduino. Please note: It is possible to directly power the stepper motor from the 5 V output of the Arduino. ULN2003 and 28BYJ-48 to Arduino Connections ULN2003 Driver Board I used a breadboard and some jumper wires to connect the driver board to an external power supply. Wiring diagram for ULN2003 driver with 28BYJ-48 stepper motor and Arduino. The connections are also given in the table below.

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 28BYJ-48 Stepper Motor Specifications Rated voltageįor more information you can check out the datasheet here. It has a built-in gearbox, which gives it some extra torque and reduces the speed drastically.īelow you can find the specifications for both the stepper motor and driver that are used in this tutorial. This motor is often used to automatically adjust the vanes of an air conditioner unit. Although it is not super accurate or powerful, it is a great motor to use for smaller projects or if you just want to learn about stepper motors. The 28BYJ-48 is one of the cheapest stepper motors you can find. Information about the 28BYJ-48 stepper motor and ULN2003 driver board
