Coding challenges for the smiley tutorial. #docs

Before we get started

Complete the smiley activity and your code will look like this:

basic.showAnimation(`
. # . # . . . . . .
. # . # . . . . . .
. . . . . . . . . .
# . . . # . . . . .
. # # # . . . . . .
`, 400)

Challenge 1

What if we want to make the face to frown when button A is pressed?

Let's make add code that will run when button A is pressed!

basic.showAnimation(`
. # . # . . . . . .
. # . # . . . . . .
. . . . . . . . . .
# . . . # . . . . .
. # # # . . . . . .
`, 400)
input.onButtonPressed("A", () => {
}) // ***

Now, we want to show a frowny face when this button is pressed. Let's plot that image.

basic.showAnimation(`
. # . # . . . . . .
. # . # . . . . . .
. . . . . . . . . .
# . . . # . . . . .
. # # # . . . . . .
`, 400)
input.onButtonPressed("A", () => {
    basic.showLeds(`
. # . # .
. # . # .
. . . . .
. # # # .
# . . . #
`, 400) // ***
})

Run your code to see if it works as expected.

Challenge 3

When button B is pressed, let's change the sad face back to a happy face. To do this, begin by adding a condition for input->on button pressed(B). Then show a smiley face inside the condition.
