### Example: rock, paper, scissors
### Example: Flip-flopping arrow
The following example shows one of three images (rock, paper, or scissors) when you shake the micro:bit:
If you press button `A`, this program will make a picture of an
arrow and show it on the LED screen. If you press button `B`, the
program will show a picture of the button upside-down.
