There are 25 bright LEDs on the micro:bit screen. Let's use them to create some cool animations!
|

|
### Happy unhappy face
|
|
|
|
Draw an unhappy face instead of the blank screen. Click on the dots
|
|
in the second ``show leds`` block until it matches the blocks below.
|
|
Now you have an **animation** (cartoon) that shows a happy face,
|
|
then an unhappy one, then a happy one again, forever (or until
|
|
you turn off your micro:bit)!
|
|
|
|
```blocks
|
|
basic.forever(() => {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
# . . . #
|
|
. # # # .
|
|
`)
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
. # # # .
|
|
# . . . #
|
|
`)
|
|
});
|
|
```
|
|
Click **Compile** to move your program to the BBC micro:bit!
|
|
|
|
### Your turn!
|
|
|
|
Pile up more ``show leds`` blocks to create an animation! Create an
|
|
animation with at least 5 pictures. What does this animation show?
|
|
|
|
```blocks
|
|
basic.forever(() => {
|
|
basic.showLeds(`
|
|
. . . . .
