Easy Driver Hook-up Guide

Stepper Motor Quickstart Guide - SparkFun Electronics

One thing worth noting is that the code also initializes the serial connection at bps. The cause also may be the speed you specified in the code. These will be your two coil wires.

9 thoughts on Controlling a Stepper Motor with an Arduino

Any stepper motor tutorial that doesn't teach that there are unipolar and bipolar motors is mostly empty. Arduino AccelStepper Library. This will allow you to power both the Arduino and the motor with the same power supply. It will set up which pins will be used on the Arduino.

If you're curious as to what the other pins on the EasyDriver do, the schematic will give you some insight. Resources and Going Further Check out these additional resources for more information and other project ideas. This gives you total control over the motor, plus size dating allowing you to move it to an exact location and hold that position.

Connect the Negative - end on a pin on another row. Swap out the components to see if it works. This is all starting to come together!

There is also an great tutoral on the bildr website. Whichever wire shows the lowest resistance against the first wire is the pair mate. Have you verified the code?

  • Again, that threaded rod needs to be moved an exact amount to print one letter after another.
  • Two wires should show some resistance between them and the first wire picked, while the other three will show no connection at all.
  • You can also find some additional examples on Brian's Easy Driver examples page.

You can use any kind of power supply desktop, wall adapter, battery power, etc. The Easy Driver gives you the capability to drive bipolar stepper motors between mA to mA per phase. So how do you get different speeds? The potentiometer on board is included to allow users the ability to select the max current provided to the motor.

Development Single Board Comp. If you need to drive four motors, you'll need something like this. Next, insert the Potentiometer into the breadboard.

Next we will need to connect the ground pins to the common ground on the breadboard. The reverse function works exactly the same as the forward function. In this case we are going to look at the switch and make a decision based on what position the switch is in and that will determine which way the motor will go. Otherwise, please post a new topic on our forums for technical assistance. For the most up-to-date code available, please check the GitHub repository.

Arduino - Sweep

It does so by powering coils inside the motor for very short periods of time. The function works just as the forward and reverse functions above, but switches between states quickly. This allows you to precisely move something with the motor in one direction, and return to the starting position exactly.

Now we have some output pins that will tell the H-Bridge what to do. Frequently Asked Questions. Repeat for the second group of three wires. To follow along with this tutorial, we recommend you have access to the following materials. Understandable, however I want to beef it up to control a treadmill motor.

How to Run a Toy DC Motor by Using Arduino (with Pictures)

You should be well on your way to adding stepper motors to your next project. The RedBoard scans the serial port for input from the user. When it is steps slow it seems to work fine. Click on the Upload button arrow pointing to the right and upload the sketch to your Arduino.

Finally, we will wire the two logic level input pins from the Arduino to the H-Bridge. Feel free to play around with this code, changing values to see what happens, and feel free to explore other code. The third function shows off the different microstepping functionality that the Easy Driver provides. First, download and unzip the example sketch. The methods described here can be used to infer how to use other motors and drivers not mentioned in this tutorial.

Hardware Hookup Connect Motor Coil Wires You will need to determine the wire pairs for each coil on the motor you plan to use. Now that we have finished with the hookup we need to start writing some code. Now that you have the hardware hooked up and ready to go, it's time to get the code uploaded. Introduction The Easy Driver gives you the capability to drive bipolar stepper motors between mA to mA per phase. There is a vast amount of information on the web regarding the Easy Driver and stepper motors in general.

The following is some very simple example code to get you up and running. This tutorial covers everything you need to know about through-hole soldering. We will also discuss how to use this motor with the EasyDriver Stepper Motor Driver board, one of the simplest driver boards around. Is this article up to date?

It is important to ensure it is placed facing the right direction so that our connections will all be made to the right locations on the chip. If you aren't familiar with the following concepts, ajman we recommend reviewing them before beginning to work with the Easy Driver. Or perhaps a remote controlled turning art installation? Another great resource is the EasyDriver Schematic. The breadboard also has a divider down the middle.

Hardware Overview
  1. There are some additional examples with this library that may be beneficial to you for use with your Easy Driver.
  2. It also sets these pins as outputs, and puts them to the proper logic levels to begin driving the motor.
  3. Get notifications of our upcoming sales, holiday hours, and new products delivered directly to your inbox!
  4. Plug the motor power supply in so the motor has power and after a few seconds try adjusting the potentiometer to adjust the motor speed.
  5. Why not show a potentiometer with a schematic turning the motor back and forth or would that be too simple?
  6. Once you have all the headers soldered on, it's time to hook up the EasyDriver to your Arduino.

The potentiometer will be used to control the motor speed and a small switch will control the direction the motor spins. This is where stepper motors come in handy. Can I use a higher voltage battery? Stepper motors can move an exact amount of degrees or steps when told to do so. With pot at low nothing happens.

How to Spin a DC Motor with the Arduino

Adding a warning that a stepper driver must not be disconnected while powered would be wise. After the requested function is completed, the pins on the Easy Driver are reset to the defaults. Pick one wire, and test this against all other wires.


The best place to look next would be the EasyDriver website. Seems like its overheating. First, set it to the lowest setting of the potentiometer. The capacitor did the trick for me. If your wiring is correct, it may be due to faulty components or connections.
