The constructor for the continuous servo is reminiscent of the RGB LED constructor, in that it is a property of the Servo object. Otherwise, it looks very similar to the Servo constructor with our PWM hat:

let continuousServo = new five.Servo.Continuous({
  controller: "PCA9685",
  pin: 0
})

There are three methods we can use with the continuous servo:

Servo.Continuous.cw([speed of 0-1]) // turns the servo clockwise
Servo.Continuous.ccw([speed of 0-1]) // turns the servo counter-clockwise
Servo.Continuous.stop() // stops the servo

Now that we know how to use it and have it wired up, let's write a quick program that lets us play with our continuous servo in the REPL.
