Welcome! This tutorial will teach how to measure the acceleration on the micro:bit in the "z" direction. Let's get started!

~

We want to display the acceleration forever. In order to do so, we need a basic->forever loop.

basic.forever(() => {
})

Let's measure the acceleration and then store in it a variable az. The acceleration is measured in milli-gravities, so a value of -1000 is equivalent to -1g or -9.81m/s^2.

basic.forever(() => {
    let az = input.acceleration("z")
})

Show the value of az on the screen.

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