EasyDriver – Hook-Up<\/strong><\/p>\n

Once you have all the headers soldered on, it\u2019s time to hook up the EasyDriver to your Arduino. Using the picture below, make all the necessary connections.<\/p>\n

Note:<\/strong> The small stepper motor looks different than the one pictured. It should have a 4-pin connector on the end. This will be attached to the 4-pin male header facing upward. Because of the nature of this particular stepper, you can hook up the connector in either orientation, i.e. either the black wire on the left or the yellow wire on the left. It will work either way. If you are using a different motor, consult its documentation to find out which wires should go where.<\/p>\n

IMPORTANT:<\/strong> Stepper motors require more power than can be supplied by the Arduino. In this example we will be powering the Uno with a 12V external supply. Notice that the power input (M+) on the EasyDriver is attached to the Vin pin on the Arduino. This will allow you to power both the Arduino and the motor with the same power supply.<\/p>\n
