步驟1：製作
它是什麼？
Shake your micro:bit and be given a random direction to walk. You will learn about variables, and using random numbers, selection and comparison logic blocks.

編程指引
運作方式
- The program uses a variable called “direction” to store a random number.
- Variables store numbers or values that can change in a computer program.
- Shake the micro:bit to set “direction” to a random number between one and three.
- The program then uses selection and comparison logic blocks to test the value of the variable.
- If “direction” is equal to 1, then an arrow pointing north shows on the micro:bit’s LED display. If “direction” is equal to 2, then the arrow points east. Otherwise, the arrow points west.
- To make the battery last longer, the program pauses for half a second after the arrow appears then clears the screen.

步驟2：編碼
步驟3：進階
- Add more directions.
- Use buttons to show icons for skipping, running, and jumping.
- Combine with the touch stopwatch program to make a motivational tool to use in sports lessons.
