Stepper Driver

Hey everyone,

How do you use a stepper driver with the Arduino? I want to use the stepper() library from Arduino and have it be encoded and used to drive a stepper motor. I saw on the website that you need an H-bridge transistor array to go in between the Arduino and the stepper motor. I'm using a bipolar stepper with 4 pins. I know I need to connect the A+ and A- and B+ and B- on the stepper driver but how do you hook the Arduino to the stepper driver??

Thank you!


Pololu sells high quality stepper drivers and provides good wiring instructions.

You may find some useful stuff in Stepper Motor Basics and in this Simple Stepper Code


You should look at the AccelStepper library too, its will ramp up and down the speed allowing
faster operation and is more flexible.
