face, or try something else.

### Repeat Forever
|
||||
|

Use the ``forever`` block to repeat your code and have a continuous animation.
|
||||
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. You can also change the pictures to make your own animation.

### Button A and B
|
||||
|
||||
Unshuffle the blocks so that the micro:bit shows "YES" when button A is pressed, and "NO" when B is pressed.
|
||||
The key idea is that all the blocks nested under `on button ... pressed` will run when that button is pressed.
|
||||
In the editor, unscramble the blocks below 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. For example,
|
||||
this program will show the word `banana` on the LED screen when you
|
||||
press `B`.
|
||||
|
||||
```blocks
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
basic.showString("AAAAA");
|
||||
input.onButtonPressed(Button.B, () => {
|
||||
basic.showString("banana");
|
||||
});

||||
```

### Shake
|
||||
|
||||
Using the data from the **accelerometer**, it is possible to detect that the BBC micro:bit is being shaken.
|
||||
You can find when someone is shaking the BBC micro:bit with the
|
||||
**accelerometer** (it finds whether the micro:bit is speeding up or
|
||||
slowing down).

### Tilting
|
||||
### Tilting with gestures
|
||||
|
||||
Aside from shake, it is also possible to detect tilt left and right, logo up and down or face up and down.
|
||||
Let's build a rock paper scissors game where you turn the micro:bit left to display paper, right to display scissors and down to display rock.
|
||||
You can also find when someone is tilting the micro:bit left or right,
|
||||
face up or face down, and logo up or logo down (the logo is the yellow
|
||||
oval picture at the top of the board).

### Pins

||||
|
||||
It is possible to use the pins (big metal bar at the bottom of the board) as button. Hold the ``GND`` button with one hand and press the ``0`` pin
|
||||
(called ``P0``) with the other hand to trigger a pin pressed.
