Constructor & Destructor Documentation

Servo

(

int

pin

)

Instantiates a servo object

Parameters

pin	servo pin number

Servo	(	int	pin,
		int	minPulseWidth,
		int	maxPulseWidth
	)

Instantiates a servo object

Parameters

pin	servo pin number
minPulseWidth	minimum pulse width, in microseconds
maxPulseWidth	maximum pulse width, in microseconds

Servo	(	int	pin,
		int	minPulseWidth,
		int	maxPulseWidth,
		int	waitAndDisablePwm
	)

Instantiates a servo object

Parameters

pin	servo pin number
minPulseWidth	minimum pulse width, in microseconds
maxPulseWidth	maximum pulse width, in microseconds
waitAndDisablePwm	if 1, PWM will be enabled only during setAngle() execution for a period of 1 second, and then turned back off. If 0, PWM will remain on afterward.
