Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...

Today in devices that use stepper motors to make beautiful music we present to you this Arduino-powered, Raspberry-Pi containing music box that uses simple stepper motors to grind out merry tunes and ...
