![]() The servo will turn left or right according to the width of this pulse. If you aren't familiar with it, a pulse is simply a square waveform that goes from 0V to another voltage for a set period of time, before returning to 0V. In order to control the rotation, we send a pulse of a variable width on the signal wire (the power and ground wires used as references for the signal). Servo motors tend to work from the 0-6V range, especially the hobby servos we are used to seeing in the Makersphere. ![]()
