magic logo activity

Show an image that points up when the logo is up.

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

~

Using the accelerometer sensor, the @boardname@ can detect when the logo is oriented up. We call that the logo up event. We will use ||input:on logo up|| to register an event handler that will run when the logo up event happens.

input.onGesture(Gesture.LogoUp, () => {
    
})

When the @boardname@ goes logo up, the code nested under the ||input:on logo up|| function will run. Let's add a line of code to show LEDs in there.

input.onGesture(Gesture.LogoUp, () => {
    basic.showLeds(`
        . . # . .
        . # # # .
        # # # # #
        . . # . .
        . . # . .
        `)
})

Run your code and try to turn around the @boardname@ to see the logo up event in action!
