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.
