A simple interface to GPIO devices with Raspberry Pi.

Created by Ben Nuttall_ and Dave Jones_.

About

Component interfaces are provided to allow a frictionless way to get started with physical computing:

.. code:: python

from gpiozero import LED
from time import sleep

led = LED(17)

while True:
    led.on()
    sleep(1)
    led.off()
    sleep(1)

With very little code, you can quickly get going connecting your components together:

.. code:: python

from gpiozero import LED, Button
from signal import pause

led = LED(17)
button = Button(3)

button.when_pressed = led.on
button.when_released = led.off

pause()

You can advance to using the declarative paradigm along with provided to describe the behaviour of devices and their interactions:

.. code:: python

from gpiozero import LED, MotionSensor, LightSensor
from gpiozero.tools import booleanized, all_values
from signal import pause

garden = LED(17)
motion = MotionSensor(4)
light = LightSensor(5)

garden.source = all_values(booleanized(light, 0, 0.1), motion)

pause()

See the chapter on Source/Values_ for more information.

.. _Source/Values: https://gpiozero.readthedocs.io/en/stable/source_values.html

The library includes interfaces to many simple everyday components, as well as some more complex things like sensors, analogue-to-digital converters, full colour LEDs, robotics kits and more. See the Recipes_ chapter of the documentation for ideas on how to get started.

Pin factories

GPIO Zero builds on a number of underlying pin libraries, including RPi.GPIO_ and pigpio, each with their own benefits. You can select a particular pin library to be used, either for the whole script or per-device, according to your needs. See the section on changing the pin factory.

.. _RPi.GPIO: https://pypi.org/project/RPi.GPIO .. _pigpio: https://pypi.org/project/pigpio .. _changing the pin factory: https://gpiozero.readthedocs.io/en/stable/api_pins.html#changing-the-pin-factory

A "mock pin" interface is also provided for testing purposes. Read more about this in the section on mock pins_.

.. _mock pins: https://gpiozero.readthedocs.io/en/stable/api_pins.html#mock-pins

Installation

GPIO Zero is installed by default in the Raspbian desktop image, available from raspberrypi.org. To install on Raspbian Lite or other operating systems, including for PCs using remote GPIO, see the Installing chapter.
