프로젝트 소개

Turn your micro:bit into a festive decoration that shows a flashing star on the LED display as soon as it gets dark.

다음 동영상을 통해 만들고 프로그래밍하는 방법을 살펴보세요.:


  • The program uses the micro:bit’s light sensor to measure the light levels.
  • It then uses an “if then else” logic block.
  • If the light levels are less than 100, the micro:bit is instructed to show two icons – a large star then a small star with pauses in between – in a forever loop on the LED display. This creates the animation.
  • A forever loop in a computer program is an instruction that repeats forever.
  • If the light levels are more than 100, the micro:bit is told to clear the screen.

  • Adjust the threshold at which the animation plays to better suit your room.
  • Instruct your micro:bit to play a festive sound on pressing button A.
  • Make other festive projects such as a jukebox which plays festive tunes, or an alarm which comes on when Father Christmas arrives on Christmas Eve!
