from gpiozero import LED

from gpiozero import RGBLED

from gpiozero import Button

from gpiozero import OutputDevice, MotionSensor, LightSensor

from gpiozero.tools import booleanized, all_values

以下几行都是等价的：

>>> led = LED(17)
>>> led = LED("GPIO17")
>>> led = LED("BCM17")
>>> led = LED("BOARD11")
>>> led = LED("WPI0")
>>> led = LED("J8:11")
