Welcome! This tutorial will help you display an arrow pointing toward the logo! Let's get started.

Using the **accelerometer** sensor, the micro:bit can detect when the **logo** is oriented **up**. We call that the **logo up** event. We will use `on logo up` to register an event handler that will run when the **logo up** event happens.
|
|
|
|
```blocks
|
|
input.onGesture(Gesture.LogoUp, () => {
|
|
|
|
})
|
|
```
|
|
|
|
When the micro:bit goes logo up, the code nested under the `on logo up` function will run. Let's add a line of code to show LEDs in there.
|
|
|
|
```blocks
|
|
input.onGesture(Gesture.LogoUp, () => {
|
|
basic.showLeds(`
|

|

|
|
. . # . .
|
|
. . # . .
|
|
`)
|
|
})
|
|
```
|
|
|
|
Run your code and try to turn around the micro:bit to see the **logo up** event in action!
