## Button Press

```python
from microbit import *

while True:
    if button_a.is_pressed() and button_b.is_pressed():
        display.scroll("AB")
    elif button_a.is_pressed():
        display.scroll("A")
    elif button_b.is_pressed():
        display.scroll("B")
    sleep(100)
```

## Detect Movement

```python
from microbit import *

while True:
    reading = accelerometer.get_x()
    if reading > 20:
        display.show("R")
    elif reading < -20:
        display.show("L")
    else:
        display.show("-")
```

## Random Numbers

```python
from microbit import *
import random

display.show(str(random.randint(1, 6)))
```

## Gestures

MicroPython is able to recognize the following gestures: up, down, left, right, face up, face down, freefall, 3g, 6g, 8g, shake. Gestures are always represented as strings. While most of the names should be obvious, the 3g, 6g and 8g gestures apply when the device encounters these levels of g-force (like when an astronaut is launched into space).

```python
from microbit import *

while True:
    gesture = accelerometer.current_gesture()
    if gesture == "face up":
        display.show(Image.HAPPY)
    else:
        display.show(Image.ANGRY)
```

## Magic-8

A Magic-8 ball is a toy first invented in the 1950s. The idea is to ask it a yes/no question, shake it and wait for it to reveal the truth.

```python
from microbit import *
import random

answers = [
    "It is certain",
    "It is decidedly so",
    "Without a doubt",
    "Yes, definitely",
    "You may rely on it",
    "As I see it, yes",
    "Most likely",
    "Outlook good",
    "Yes",
    "Signs point to yes",
    "Reply hazy try again",
    "Ask again later",
    "Better not tell you now",
    "Cannot predict now",
    "Concentrate and ask again",
    "Don't count on it"
    "My reply is no",
    "My sources say no",
    "Outlook not so good",
    "Very doubtful",
]

while True:
    display.show("8")
    if accelerometer.was_gesture("shake"):
        display.clear()
        sleep(1000)
        display.scroll(random.choice(answers))
```
