Story

This project was inspired by this project: https://www.andreagrandi.it/2016/02/08/using-a-light-sensor-with-bbc-microbit-and-micropython/. I have added instructions on how to build this using the block based editor: https://makecode.microbit.org/.

Code

Light Sensor Code

from microbit import *

while True:
    lightSensor = pin0.read_analog()
    if lightSensor > 512:
        sun = Image("90909:"
                    "09990:"
                    "99999:"
                    "09990:"
                    "90909")
        display.show(sun)
    elif lightSensor < 512:
        moon = Image("99900:"
                     "09990:"
                     "00990:"
                     "09990:"
                     "99900")
        display.show(moon)
