  9. Servo (radio control) - Wikipedia

    en.wikipedia.org/wiki/Servo_(radio_control)

    The servo is controlled by three wires: ground, power, and control. The servo will move based on the pulses sent over the control wire, which set the angle of the actuator arm. The servo expects a pulse every 20 ms in order to gain correct information about the angle. The width of the servo pulse dictates the range of the servo's angular motion.
