Welcome! This tutorial will teach how to measure the acceleration on the micro:bit in the "z" direction. Let's get started!
### ~
To create a new script, go to the [Create Code](/microbit/create-code) page and tap *New Project* under **Touch Develop**.
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)
})
```
