Before we get started

Complete the following guided tutorial:

At the end of the tutorial, click keep editing. Your code should look like this:

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

Challenge 1

Add a pause of 3000 milliseconds (3 seconds) after showing the number so that the number won't immediately disappear in the next challenge.

input.onPinPressed("P0", () => {
    let x1 = Math.random(11)
    basic.showNumber(x1, 150)
    basic.pause(3000) // ***
})

Challenge 2

If the rating x is between 0 and 3 (strictly less than 4), display the text "HORRIBLE!".

input.onPinPressed("P0", () => {
    let x2 = Math.random(11)
    basic.showNumber(x2, 150)
    basic.pause(3000)
    if (x2 < 4) {
        basic.showString("HORRIBLE!", 150) // ***
    }
})

Challenge 3

@video td/videos/love-meter-3

If the rating is between 4 and 7, display the text "MEDIOCRE!" else display the text "MATCHED!"

input.onPinPressed("P0", () => {
    let x3 = Math.random(11)
    basic.showNumber(x3, 150)
    basic.pause(3000)
    if (x3 < 4) {
        basic.showString("HORRIBLE!", 150) // ***
    } else if (x3 < 8) {
        basic.showString("MEDIOCRE!", 150) // ***
    }
    else {
        basic.showString("MATCHED!", 150) // ***
    }
})

Challenge 4

Use basic->plot image or basic->show animation to display images and animations instead of text for each case.
