This recipe will teach you the basic logic of how to control a motor; however, this is not a typical way of connecting a motor to the Arduino. It is recommended that you first understand this recipe and then apply the following one, Controlling motors with transistors.

Getting ready

Following are the ingredients required to execute this recipe:

  • An Arduino board connected to a computer via USB
  • A 220-ohm resistor
  • A very small DC motor—usually a vibration motor will work—that can be found in old (and new) mobile phones or can typically be brought from websites such as Sparkfun or Adafruit
