@ -5,12 +5,12 @@ Are you ready to build cool BBC micro:bit programs?
Here are some challenges for you. Unscramble the blocks in the editor
to make real programs that work!
### Blinky face
### Happy face
You should see three blocks in the editor to the left.
These are a block with a smiley face, ...
```shuffle
```blocks
basic.forever(() => {
basic.showLeds(`
. . . . .
@ -29,65 +29,18 @@ basic.forever(() => {
});
```
### Show LEDs
Draw something in the editor with this block. You can draw another
smiley face, or try something else.
```shuffle
basic.showLeds(`
. . . . .
. # . # .
. . . . .
# . . . #
. # # # .
`)
```
To move your program from your computer to the BBC micro:bit:
* Connect your micro:bit to the computer with the USB cable.
* Click **Compile**.
* Drag and drop the new file whose name ends in **.hex** into the **MICROBIT** window.
* Wait until the yellow light stops blinking!
### Show animation forever
### Happy unhappy face
Show one picture after another by snapping blocks together to create an
animation (like a cartoon)!
Let's draw an unhappy face instead of the blank screen. Click on the dots in the ``show leds`` block
until it matches the blocks below.
```blocks
basic.showLeds(`

* Click **Compile**.
* Drag and drop the new file whose name ends in **.hex** into the **MICROBIT** window.
* Wait until the yellow light stops blinking!
### Repeat Forever
Make an animation that never stops with the ``forever`` block.
Unscramble these blocks in the editor to make an animation that first
shows a happy face, then an unhappy face, then a happy face, and never
stops.
```shuffle
basic.forever(() => {
basic.showLeds(`

### Your turn!
You can also change the pictures to make your own animation.
Make your own awesome animation with the ``show leds`` and ``forever``
blocks.
Pile up more ``show leds`` blocks to create your animation! Create an animation with at least 5 images.
```blocks
basic.forever(() => {
basic.showLeds(`

#### ~hint
You can make your animation longer if you use more than two pictures.
You can find the ``show leds`` block under the **Basic** category.

### Button A and B
This program will show the word `banana` on the LED
screen when you press button `B`.
screen when you press button `A`.
```blocks
input.onButtonPressed(Button.B, () => {
input.onButtonPressed(Button.A, () => {
basic.showString("banana");
});
```
Now try to unscramble these blocks in the editor so that the micro:bit
shows **YES** when you press button `A` and **NO** when when you press
button `B`. All of the blocks under `on button A pressed` or
`on button B pressed` should run when you press that button.
shows **apple** when you press button `B`.
```shuffle
input.onButtonPressed(Button.A, () => {
basic.showString("YES");
});
input.onButtonPressed(Button.B, () => {
basic.showString("NO");
basic.showString("apple");
});
```
