# magic logo challenges

Coding challenges for magic logo.

## Before we get started

Complete the [magic logo](/lessons/magic-logo/activity) activity and your code will look like this:

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

```


### Challenge 1
