Types

type PWM

type PWM interface {
	SetMicroseconds(us int) error
}

A PWM interface implements access to a pwm controller.

	PWM PWM

	Minus, Maxus int
}

func New

func New(pwm PWM) *Servo

New creates a new Servo interface.

func (*Servo) SetAngle

func (s *Servo) SetAngle(angle int) error

SetAngle sets the servo angle.
