Our latest project uses an array of parts to build three separate breadboard projects. Follow along as we put Projects in Motion, showing you how to control three different motor types with little more than a few components, wire, and a power source.

Rather than shop for them, we’re fabbing our own with the laser cutter and Makerbot. Earlier this week, Jett worked out the proper dimensions to fit a plate to a motor shaft. He did this by measuring out a range of holes and then cutting them in quarter inch acrlyic. Once they came out of the laser, he tried pushing the motor into each of the holes until he found the ‘goldilocks fit.’ Once we had a plate, he used the same process to cut a series of holes in the plate that could be threaded with M3 screws. This setup allows us to attach anything to a motor.
