truth or dare tutorial

~avatar avatar

The Truth or dare! game works as follows: a player spins the BBC micro:bit on the table. When the micro:bit stops spinning, the player pointed by the arrow (displayed on screen) must press the button "A" to see if she has to provide a truth or a dare.

Rebuild the game!

The blocks have been shuffled! Put them back together so that...

• an up arrow is displayed when the micro:bit is powered on.
• on button A is pressed,
  • randomly display "TRUTH" or "DARE" on the screen
  • show the up arrow again.

input.onButtonPressed(Button.A, () => {
    let random = Math.random(2)
    if (random == 0) {
        basic.showString("TRUTH")
    } else {
        basic.showString("DARE")
