Dice

Introduction

Let’s turn the micro:bit into a dice! (Want to learn how the accelerometer works? Watch this video).

Step 1

We need 3 pieces of code: one to detect a throw (shake), another to pick a random number, and then one to show the number.

Place the ||input:on shake|| block onto the editor workspace. It runs code when you shake the micro:bit.

input.onGesture(Gesture.Shake, () => {

})

Step 2

Get a ||basic:show number|| block and place it inside the ||input:on shake|| block to display a number.

input.onGesture(Gesture.Shake, () => {
    basic.showNumber(0)
})

Step 3

Put a ||Math:pick random|| block in the ||basic:show number|| block to pick a random number.

input.onGesture(Gesture.Shake, () => {
    basic.showNumber(Math.randomRange(0, 10))
})

Step 4

A typical dice shows values from 1 to 6. So, in ||Math:pick random||, don’t forget to choose the right minimum and maximum values!

input.onGesture(Gesture.Shake, () => {
    basic.showNumber(Math.randomRange(1, 6))
})

Step 5

Use the simulator to try out your code. Does it show the number you expected?

Step 6
