Get up!

1. korak: Napravi

Što je to?

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.

Ova dva videa prikazuju što ćeš napraviti i kojim kodom:

Kako to radi

• 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.

Što ti treba

• micro:bit (or use the simulator in the online editors)
• Uređivač MakeCode ili Python
  
• battery pack (optional but recommended)

3. korak: Unaprijedi

• Change the alarm sound.
• Replace the sun icon with motivational messages that can help you to start your day.
