snowflake fall blocks challenges

Coding challenges for snowflake fall.

Before we get started

Complete the snowflake fall activity and your code will look like this:

basic.forever(() => {
    basic.showLeds(`
        . . . . .
        . . # . .
        . # # # .
        . . # . .
        . . . . .
        `)
    basic.showLeds(`
        . . # . .
        . # . # .
        # . . . #
        . # . # .
        . . # . .
        `)
})

To finalize our snowflake fall, let's add a different snowflake pattern.

basic.forever(() => {
    basic.showLeds(`
        . . . . .
        . . # . .
        . # # # .
        . . # . .
        . . . . .
        `)
    basic.showLeds(`
        . . # . .
        . # . # .
        # . . . #
        . # . # .
        . . # . .
        `)
    basic.showLeds(`
        . # . # .
        # # # # #
        . # . # .
        # # # # #
        . # . # .
        `)
})

• Run your program and see if it works.
