In this article, I will show you how to interface a 5-volt Stepper Motor in Arduino.

Stepper motors are a kind of DC motor that moves in small steps. With very precise motion, stepper motors are the best choice for projects that require precise and accurate movement.

Today, I will show you the ropes in using a stepper motor to integrate in your next project.

Step 1: Required Arduino Components
5V Stepper Motor Arduino Interfacing: Steps in Creating the Device
To start off, this project will have two parts: the Arduino Device and the Program. The first thing to do is to collect the hardware components and make the device. To do that, you will be needing the following:

Quantity Components
1 Arduino Uno
1 Unipolar Stepper Motor
1 ULN2003 Motor Driver

Step 2: Connecting the Arduino Components

Now you are ready to connect the components to the Arduino Uno. Attach the stepper motor to the motor driver. Next is to connect the four pins of the motor driver to the Arduino’s digital pins. Take note of the order of the pins.

Step 3: The Arduino Code
There is already a library for the stepper motor preinstalled in the Arduino IDE called “Stepper”. All you need to do is copy the code and upload it to the Arduino.

Now upload the sketch to the Arduino.

Step 4: Test Run
After you successfully upload the sketch, the stepper motor will rotate clockwise and counterclockwise according to the indicated RPM.

So there you have it! 5V Stepper Motor Arduino Interfacing. This project is intimidating at first but you will see that it is fairly easy to do. You can combine this with other Arduino projects and build an awesome system!
