OOPic Servo Motor Controller
This project build to drive a standard Radio Control (RC) Servo which is a motorized device that moves its actuator to a position specified by a controlling electronic signal. Inside is a complete servo system including motor, gearbox, feedback device (pot), servo control circuitry, and drive circuit. Several sizes of servos exist that range from very fast to very powerful. These devices were popularized by the Radio Control hobbyist movement and, as a result, are very inexpensive.
