Festive decoration

第 1 步:制作


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



  • 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.

10                           '90909'))
11        sleep(500)
13                       '09090:'
14                       '00900:'
15                       '09090:'
16                       '00000'))
17        sleep(500)
18    else: display.clear()
19    sleep(500)


  • 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!
