Control a DC Motor with Arduino (Lesson #16)

Complete Arduino tutorial playlist: https://www.sciencebuddies.org/science-fair-projects/references/how-to-use-an-arduino

Learn how to control a DC motor with an Arduino and a transistor and an external power supply. This approach only lets you spin the motor in one direction - check out the next video in our series to learn how to make the motor reverse directions with an H-bridge.
