LightSensor가 빛과 어둠을 감지하도록하십시오 :

from gpiozero import LightSensor

sensor = LightSensor(18)

while True:
    sensor.wait_for_light()
    print("It's light! :)")
    sensor.wait_for_dark()
    print("It's dark :(")

조명이 변경되면 함수를 실행하십시오.

from gpiozero import LightSensor, LED
from signal import pause

sensor = LightSensor(18)
led = LED(16)

sensor.when_dark = led.on
sensor.when_light = led.off

pause()

 감지 된 밝기에 따라 PWMLED 변경 밝기를 설정하십시오.

from gpiozero import LightSensor, PWMLED
from signal import pause

sensor = LightSensor(18)
led = PWMLED(16)

led.source = sensor.values

pause()
