Get up!

Primeiro passo: o projeto

O que é?

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.

Estes dois vídeos mostram o que você fará e como desenvolver o código:

Como funciona:

• 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.

Itens necessários:

• micro:bit (or use the simulator in the online editors)
• Editor MakeCode ou Python;
• pacote de bateria (opcional mas recomendado)

Segundo passo: é hora de programar

1from microbit import *
2import music
3
4while True:
5    if display.read_light_level() > 70:
6        display.show(Image(
7        "90909:"
8        "09990:"
9        "99999:"
10        "09990:"
11        "90909"))
12        music.play(music.DADADADUM)    
13    else:
14        display.clear()
15        

Terceiro passo: vamos deixar o código ainda melhor

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