You can change this value if you want if you are using a different type of stepper motor or setup. This means it takes 200 steps to rotate 360 degrees. In this example we will be using the motor in full-step mode. Next I defined how many steps the motor takes to rotate 1 revolution. More information about this library can be found on the Arduino website. The sketch starts by including the Stepper.h Arduino library. Step on revolution in the other direction: Set the PWM and brake pins so that the direction pins can be used to control the motor: Stepper myStepper = Stepper(stepsPerRevolution, dirA, dirB) Initialize the stepper library on the motor shield: Define number of steps per revolution: * Example sketch to control a stepper motor with Arduino Motor Shield Rev3, Arduino UNO and Stepper.h library. It comes with two separate channels, called A and B, that you can use to drive 2 DC motors, or 1 stepper motor when combined. With the shield, you can drive DC motors, a stepper motor, relays, and solenoids. The Arduino Motor Shield Rev3 is built around the L298 dual full-bridge driver, made by STMicroelectronics.

This one from Adafruit works great at 12 V and doesn’t draw too much current (350 mA). Try to find a stepper motor that can run at 5-12 V and doesn’t exceed the 2 A current limit. In this tutorial I used a bipolar stepper motor with 4 wires.
