I love Arduino’s!
One of the main reasons I was so excited about Arduino’s potential back when I discovered them in 2006 was simple: controlling motors! Arduino’s control small motors very easily; in fact, I’ve done a number of videos covering How to Control a Servo with Arduino, How to Control a Stepper with Arduino, and How to Accurate Control Steppers.
