#Stepper motor arduino driver
Step motor driver board (we’ll use the ULN2003) If not, you’ll need more wiring for your breadboard. If you choose to get the ULN2003 driver board (which we highly recommend for this project), then the components for this project get a lot simpler. To keep everything working properly, make sure to power your step motor separately. For the simple demonstration sketch in this guide, we’ll be using the 5V pin on the Arduino, but it can cause performance problems or even damage your board if you expand this project without carefully managing your power consumption. It’s also important to point out that since the step motor draws a high current, it’s best to use a separate power source for your final projects, rather than powering it off the Arduino. This library is built into the Arduino IDE, so you won’t need to do anything special to enable it, but you can check out the documentation at the link above to see how it will work. This library will let you set the speed or number of steps that your motor will take with just a single line of code. We’ll also be using the built-in Stepper.h library which will make sending instructions to the step motor much simpler. While you can find the IC on its own and wire it up manually, it’s a lot easier to find a driver board with the IC integrated directly into it. This driver board allows the low current Arduino to control the high current step motor. The step motor uses a high current, which means an IC like the ULN2003 is needed to control it. To control this step motor, you’ll also need a microcontroller that will handle all the complex movements. There are many types of Arduino step motors, but for this project we’ll be using the common 28BYJ-48. While this makes stepper motors slower than servos, they’re also much more precise, allowing for extremely controlled movement with minimal vibration. Each coil is activated in succession, magnetically drawing the rotor towards it, rotating it 90 degrees.
In a step motor, four coils form a ring around a rotor.

This guide will show you how to control a stepper motor with Arduino boards.Īrduino step motors work similarly to servos, but with some key differences that make it easier to gain precise control over the motor’s movements.
Step motors can take your projects further, letting you rotate a motor with more precision and stability than you get from servo motors. In a previous guide, we’ve discussed how to use servos to control physical objects with your Arduino.
