A simple interface to GPIO devices with Raspberry Pi.

Created by `Ben Nuttall`_ of the `Raspberry Pi Foundation`_, `Dave Jones`_, and
other contributors.

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()

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 :doc:`recipes` page for ideas on
how to get started.

Install
=======

GPIO Zero is installed by default in Raspbian Jessie, available from
`raspberrypi.org`_. To install on Jessie Lite or other operating systems,
including for PCs using remote GPIO, see the :doc:`installing` page.

Documentation
=============

Comprehensive documentation is available at https://gpiozero.readthedocs.io/.
