Code

Duration: ~30 minutes

We are going to add code to open the mouth proportionally to the amount of light on the micro:bit. The code is in a loop so we’ll continually read the light level and map it to an angle using the ||pins:map|| function.

basic.forever(() => {
    pins.servoWritePin(AnalogPin.P0, pins.map(
        input.lightLevel(),
        0,
        255,
        30,
        150
    ))
})
