Stepper Motor
In this project, you'll learn how to control a stepper motor with the Arduino.A stepper motor can turn complete circles in either directions in increments of one step at a time. A ULN2003 Darlington driver chip is needed to control the motor.
Parts needed:

1 | Making the connections
The stepper motor has five connection wires: red, orange, yellow, pink and blue. These five wires are already connected to the ULN2003 Darlington driver chip. From the ULN2003 Darlington driver chip, six connections are made to the Arduino:

2 | Create a new BareMinimum program and type in this code. |

3 | Run the program and you should see the stepper motor turning clockwise and counter clockwise. | |
