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.

input.onLogoUp(() => {
    
})

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.

input.onLogoUp(() => {
    basic.showAnimation(`
        . . # . .
        . # # # .
        # # # # #
        . . # . .
        . . # . .
        `)
})

Run your code and try to turn around the micro:bit to see the logo up event in action!
