Once the object is on a green light turns on so it indicates that it's on and a tone plays at half speed, the knob indicates the pitch on what level it is.
let value = 0
pins.A2.setPull(PinPullMode.PullUp)
music.setVolume(128)
forever(function () {
    if (!(pins.A2.digitalRead())) {
        light.setAll(0x00ff00)
        value = pins.A1.analogRead()
        music.playTone(value, music.beat(BeatFraction.Half))
    } else {
        light.clear()
    }
})
