Servo Motor Control with PIC16F84


Posted on Feb 7, 2014

This simple micro-control circuit controls a servo motor according to a 3-state switch. A servo motor acts as an actuator in 3 position. It has 3 wires, one for VCC, one for Ground and another one for position control. The last signal is a single pulse with variable width. The pulse width can vary between 1 and 2 mSec. An 1 mSec pulse width turns
