설명
- The program uses variables called “A” and “B” to store the number of animals or plants counted.
- Variables store numbers or values that can change in a computer program.
- At the beginning of the program, “A” and “B” are set to zero and zero is shown on the LED display. You should always give variables an initial value in a computer program like this.
- Press button A each time you see a particular animal or plant, for example, a duck, and each time one will be added to “A”.
- Press button B each time you see another plant or animal of interest, for example, a goose, and each time one will be added to “B”.
- Shake your micro:bit to show the totals on the LED display.
