SERVO MOTOR
The servo motor is a standard remote-control hobby servo motor. It has
a built-in position feedback loop, based on an internal potentiometer,
which enables its position to be commanded directly.
The servo is an extremely easy component to interface with a microcontroller. Power is supplied with a 5-V source and control is provided through a 50-Hz PWM signal. The PWM signal is connected to the FTIOB output port on the H8/3664 through a 7404 inverter, which is used as a buffer.
