|
|
```
|
|
|

Now, we want to show a frowny face when this button is pressed. Let's show the LEDs.
|
|
|
|
```blocks
|
|
basic.showAnimation(`
|
|
. # . # .
|
|
. # . # .
|
|
. . . . .
|
|
# . . . #
|
|
. # # # .
|
|
`)
|
|
basic.showAnimation(`
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
`)
|
|
input.onButtonPressed(Button.A, () => {
|
|
basic.showAnimation(`
|
|
. # . # .
|
|
. # . # .
|
|
. . . . .
|
|
. # # # .
|
|
# . . . #
|
|
`)
|
|
})
|
|
|
|
```
|
|
|
|
* 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 `on button pressed` *B*. Next, show LEDs as a smiley face inside the condition.
