Communication protocol

• The servo motor controller is controlled by pulse width modulation.
• Rotation speed and direction are determined by the high pulse duration, in the 1000us–2000us range.
• To keep rotation smooth, the servo requires a 20 ms pause between pulses.
• When the pulse length decreases from 1500us, the servo will gradually start rotating faster counterclockwise.
• Conversely, when the pulse length increases from 1500us, the servo will gradually start rotating faster clockwise.
