Welcome! This tutorial will teach how design a **snowfall animation**. Let's get started!

Let's start by creating a `forever` loop that will allow us to repeat the show LEDs code. Any code in the `forever` loop will repeat in the background... forever.
|
|
|
|
|
|
```blocks
|
|
basic.forever(() => {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . # . .
|
|
. # # # .
|
|
. . # . .
|
|
. . . . .
|
|
`)
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
`)
|
|
})
|
|
```
|
|
|
|
The next step is to add two `show LEDs` blocks inside the `forever` loop to repeat an animation.
|
|
|
|
```blocks
|
|
basic.forever(() => {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . # . .
|
|
. # # # .
|
|
. . # . .
|
|
. . . . .
|
|
`)
|
|
basic.showLeds(`
|
|
. . # . .
|
|
. # . # .
|
|
# . . . #
|
|
. # . # .
|
|
. . # . .
|
|
`)
|
|
})
|
|
```
|
|
|
|
Run your code in the simulator or download it to your @boardname@ to see what happens!
