Connect a Circuit to Win

Introduction

Let’s detect a WIN when a circuit is completed on the micro:bit!

Step 2

We ‘ll start by adding code to the ||input:on pin [P0] [pressed]||
container already in the workspace.

💡 You can click the arrow next to ||input:P0|| and change it to another pin if you prefer.

input.onPinPressed(TouchPin.P0, function () {})

Step 3

Open the ||basic:Basic|| category
and drag ||basic:show string ["WIN!"]||
into the empty ||input:on pin [P0] [pressed]|| container to display a message.

input.onPinPressed(TouchPin.P0, function () {
    basic.showString("WIN!")
})

Step 4

Click the pin marked 0 in the simulator to give your code a try.

Step 5

Add some drama with music.

Open the ||music:Music|| category and
drag ||music:play [melody] [in background]||
into the top of the ||input:on pin [P0] [pressed]|| container in the workspace.

input.onPinPressed(TouchPin.P0, function () {
    music._playDefaultBackground(music.builtInPlayableMelody(Melodies.Dadadadum), music.PlaybackMode.InBackground)
    basic.showString("WIN!")
})

Step 6

Test again by clicking P0 in the simulator

Your program should play a song and scroll the word “WIN!”.

💡 You may need to unmute the simulator to hear your music.

Step 7

If you have a micro:bit connected, click |Download| and transfer your code.

Now you’re ready to attach your micro:bit to your project and try it out!

💡 Note that the pin pressed block requires the pin to be pressed and released before it will trigger.

    basic.showString("WIN!")

input.onPinPressed(TouchPin.P0, function () { })

basic.showIcon(IconNames.Yes)
input.onButtonPressed(Button.A, function () {
    music.play(music.builtinPlayableSoundEffect(soundExpression.sad), music.PlaybackMode.InBackground)
    music._playDefaultBackground(music.builtInPlayableMelody(Melodies.Funeral), music.PlaybackMode.InBackground)
    basic.showString("Loss")
})
input.onPinPressed(TouchPin.P0, function () {
    music.play(music.builtinPlayableSoundEffect(soundExpression.sad), music.PlaybackMode.InBackground)
    basic.showString("WIN!")
})
