Fairly straightforward code. See attached pdf for block-based example too.
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:"
