Welcome! This tutorial will teach how to program a game of truth or dare on the micro:bit. Let's get started!
### ~
Begin by using Show LEDs to create an "up-arrow" image, which will point to someone.
```blocks
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
```
Now let's create a condition to know when button `A` is pressed so that we can display "truth" or "dare" on the micro:bit. We want the BBC micro:bit to randomly choose whether to display "truth" or display "dare". We can use accomplish this by using `pick random (1)`.
```blocks
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
input.onButtonPressed(Button.A, () => {
let random = Math.random(2)
})
```
Now let's display the appropriate message for each scenario of `random`.
```blocks
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
input.onButtonPressed(Button.A, () => {
let random = Math.random(2)
if (random == 0) {
basic.showString("TRUTH")
} else {
basic.showString("DARE")
}
})
```
Notice how the arrow didn't display again after pressing button `A`. Let's add a line of code that displays the arrow again.
