Communication Protocol

The Servo motor controller is controlled through pulse width modulation.

Rotational speed and direction are determined by the duration of a high pulse, in the 1000us–-2000us range.

In order for smooth rotation, the servo needs a 20 ms pause between pulses.

As the length of the pulse decreases from 1500us, the servo will gradually rotate faster in the counter-clockwise direction.

Likewise, as the length of the pulse increases from 1500us, the servo will gradually rotate faster in the clockwise direction, as can be seen in the figure below:
