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](/microbit/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("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("P0", () => {
    let x = Math.random(11)
})
```

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

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