Turn your micro:bit into a light-sensitive alarm to help you get up in the morning. You'll learn how to use infinite loops, and selection with comparison logic.

- The program uses the micro:bit’s LED display as a light sensor.
- Selection ('if... else') and comparison logic (> 70) are used so that if the light level is above a certain amount, a sun icon appears and it makes a noise; else, it clears the screen.
- If the light level is greater than (>) 70, a sun appears on the LED display, telling you it’s time to get up.
- The program uses an infinite loop to keep sensing the light level.
- You can adjust the threshold at which the sun appears. Use larger numbers to make it less sensitive to light, so the alarm only goes off when it's brighter - or smaller numbers to make it more sensitive to light.
- micro:bit (or use the simulator in the online editors)
- MakeCode 또는 Python 편집기
- battery pack (optional but recommended)
