To create a new script, go to the [Create Code](/microbit/create-code) page and tap `New Project` under `Block Editor`.

Welcome! This activity 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 `forever` loop.
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
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`.
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
basic.forever(() => {
|
||
|
|
let az = input.acceleration(Dimension.Z)
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
Show the value of `az` on the screen.
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
basic.forever(() => {
|
||
|
|
let az = input.acceleration(Dimension.Z)
|
||
|
|
basic.showNumber(az)
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
