This means you'll have to figure out a way to alternate steps between motors. The Arduino isn't great at doing two things at once so you'll only be able to drive one motor at a time. Updated Issue Details I have a stepper motor with either 4, 6, or 8 lead wires available to connect to a stepper drive. ![]() Can you make these motors rotate in such a way that they'll cause the robot to turn? Note that when you tell the motor class to go X steps, it doesn't return until those steps are complete. Now that you've got the basics complete, try making a change to the program to control two motors (hint: see the comment near the top of the main code). Note that the stepper motor is not particularly fast so you'll want to be efficient with your movement and finding a short path. All we need here is to see how the 4 wires coming. If you have some documentation about your motor than you are set. The example program reads from the serial port and either moves forward when it receives and "f" or backwards when it receives a "b". Step 1: Confirm the wiring of your motor. Start by loading the example program included in this repository on to the Arduino. See the below wiring guide, but the important part is simply to power the Arduino, connect the GND and +5v lines to the controller and then to connect the 4 IN pins from the motor controller to the Arduino's ports. Wiring the Arduino and stepper motors should be relatively simple. For your motors you'll need to look up the datasheets online to determine how many steps they have per complete revolution. ![]() ![]() When you control a stepper motor you tell it how many "steps" it should take. Stepper motors are special in that the forsake speed for extreme accuracy. For this project you'll be programming the Arduino to control stepper motors and potentially to control a 3D printed robot.
