zoomer challenges

The acceleration function.

Challenge 0

Great job! You have successfully completed the zoomer tutorial . You have created a script that measures the acceleration on the micro:bit in the "z" direction of a 3D world.

basic.forever(() => {
    let millig = input.acceleration("z")
    basic.showNumber(millig, 150)
    basic.pause(100)
})

Challenge 1

Create a new variable called milliX that holds the acceleration in the "x" direction or the horizontal direction.

basic.forever(() => {
    let millig1 = input.acceleration("z")
    basic.showNumber(millig1, 150)
    basic.pause(100)
    let milliX = input.acceleration("x") // ***
})

Run the code to see if it works as expected.

Challenge 2

If Button A is pressed, we want to show the acceleration in the "x" direction by adding an if statement that checks to see if Button A is pressed and then calling the show number method passing in milliX as the number.

basic.forever(() => {
    let millig2 = input.acceleration("z")
    basic.showNumber(millig2, 150)
    basic.pause(100)
    let milliX1 = input.acceleration("x")
    if (input.buttonIsPressed("A")) {
        basic.showNumber(milliX1, 150) // ***
    }
})

Run the code to see if it works as expected.

Challenge 3

If Button B is pressed, program the micro:bit to display the acceleration in the "y" direction.

You can do this by storing the acceleration in a variable: var milliY := input->acceleration("y").

Then add an if statement that checks if Button B is pressed: if input-> button is pressed ("B") then.

Inside of the if statement, add basic->show number(milliY, 150), which will display the acceleration in the "y" direction.
