Welcome! This tutorial will help you create a love meter with the BBC micro:bit. Let's get started!

~

To create a new script, go to the Create Code page and tap New Project under Touch Develop.

Begin by registering an event with input->on pin pressed(PO) to know when someone is holding pin P0 and pin Gnd.

input.onPinPressed(TouchPin.P0, () => {
})

We are going to create a meter that displays a random number from 0 to 10. We use 11 as math->random(n) returns a number between 0 and n-1.

input.onPinPressed(TouchPin.P0, () => {
    let x = Math.random(11)
})

Finally, let's show that number on the micro:bit.

input.onPinPressed(TouchPin.P0, () => {
    let x_ = Math.random(11)
    basic.showNumber(x_, 150)
})
