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.

Proximity Switches: http://amzn.to/1oHRPru

But another great thing about Arduino’s is they make it very easy to control large motors – like the brushed DC gearmotors in this video buy using a motor controller.

In this video tutorial, we walk through a simple example in the Arduino IDE to show just how easy it is to get up and running to start, stop, control direction and speed of a large motor with Arduino!

In the second example, we use two proximity sensors as limit switches and two potentiometers to allow on-the-fly speed adjustment!
