Code

Remote.uf2

Arduino
This code is responsible for sensing when a task is complete or when a sensor has been activated. Once all the sensors have been interacted with or activated, the "remote" will turn all its neo-pixels blue
network.onInfraredReceivedNumber(function (found_id) {
    if (found_id == Source_1) {
        light.setPixelColor(Source_1, 0x00ff00)
        found_1 = true
    }
    if (found_id == Source_2) {
        light.setPixelColor(Source_2, 0x00ff00)
        found_2 = true
    }
    if (found_id == Source_3) {
        light.setPixelColor(Source_2, 0x00ff00)
        found_3 = true
    }
    if (found_id == Source_4) {
        light.setPixelColor(Source_4, 0x00ff00)
        found_4 = true
    }
})
let found_4 = false
let found_3 = false
let found_2 = false
let found_1 = false
let Source_4 = 0
let Source_3 = 0
let Source_2 = 0
let Source_1 = 0
Source_1 = 1
Source_2 = 2
Source_3 = 3
Source_4 = 4
found_1 = false
found_2 = false
found_3 = false
found_4 = false
light.clear()
forever(function () {
    if (found_1 && found_2 && (found_3 && found_4)) {
        music.playSound(music.sounds(Sounds.BaDing))
        while (true) {
            light.showRing(
            `blue blue blue blue blue blue blue blue blue blue`
            )
            pause(200)
        }
    }
})

Module 1.uf2

Arduino
Responsible for sending out various infrared signals after interacting with the various sensors installed in the Circuit playground express
let shake_v = 0
let sound_v = 0
let light_v = 0
input.onGesture(Gesture.Shake, function () {
    shake_v += 1
})
input.onLoudSound(function () {
    sound_v += 1
})
input.onLightConditionChanged(LightCondition.Bright, function () {
    light_v += 1
})
forever(function () {
    pause(500)
    light.setAll(0xff0000)
    if (shake_v >= 1) {
        network.infraredSendNumber(1)
        light.setPixelColor(0, 0x00ff00)
    }
    if (sound_v >= 1) {
        network.infraredSendNumber(2)
        light.setPixelColor(4, 0x00ff00)
    }
    if (light_v >= 1) {
        network.infraredSendNumber(3)
        light.setPixelColor(7, 0x00ff00)
    }
    pause(200)
    light.clear()
})

Module 2.uf2

Arduino
Responsible for managing the Ultrasound sensor and sending out a signal once the sensor has been activated
let distance = 0
let ultra_v = 0
forever(function () {
    pins.A2.digitalWrite(false)
    control.waitMicros(2)
    pins.A2.digitalWrite(true)
    control.waitMicros(10)
    pins.A2.digitalWrite(false)
    distance = pins.A1.pulseIn(PulseValue.High) / 58
    if (distance >= 0.25 && distance <= 50) {
        ultra_v += 1
        light.setPixelColor(0, 0x00ff00)
    } else {
        light.clear()
    }
    console.logValue("distancecm", distance)
    pause(100)
    if (ultra_v >= 1) {
        network.infraredSendNumber(4)
        light.setPixelColor(9, 0x00ff00)
    }
    pause(1000)
})
