Remote GPIO Recipes
|
|
===================
|
|
|
|
.. currentmodule:: gpiozero
|
|
|
|
The following recipes demonstrate some of the capabilities of the feature of the
|
|
GPIO Zero library. Before you start following these examples, please read up on
|
|
preparing your Pi and your host PC to work with :doc:`remote_gpio`.
|
|
|
|
Please note that all recipes are written assuming Python 3. Recipes *may* work
|
|
under Python 2, but no guarantees!
|
|
|
|
LED + Button
|
|
============
|
|
|
|
Let a button on one Raspberry Pi control the LED of another:
|
|
|
|
.. literalinclude:: examples/led_button_remote_1.py
|
|
|
|
LED + 2 Buttons
|
|
===============
|
|
|
|
The LED will come on when both buttons are pressed:
|
|
|
|
.. literalinclude:: examples/led_button_remote_2.py
|
|
|
|
Multi-room motion alert
|
|
=======================
|
|
|
|
Install a Raspberry Pi with a motion sensor in each room of your house, and have
|
|
an LED indicator showing when there's motion in each room:
|
|
|
|
.. literalinclude:: examples/multi_room_motion_alert.py
|
|
|
|
Multi-room doorbell
|
|
===================
|
|
|
|
Install a Raspberry Pi with a buzzer attached in each room you want to hear the
|
|
doorbell, and use a push button as the doorbell:
|
|
|
|
.. literalinclude:: examples/multi_room_doorbell.py
|
|
|
|
This could also be used as an internal doorbell (tell people it's time for
|
|
dinner from the kitchen).
|
|
|
|
Light sensor + Sense HAT
|
|
=========================
|
|
|
|
The `Sense HAT`_ (not supported by GPIO Zero) includes temperature, humidity and
|
|
pressure sensors, but no light sensor. Remote pins allow an external light
|
|
sensor to be used as well. The Sense HAT LED display can be used to show
|
|
different colours according to the light levels:
|
|
|
|
.. literalinclude:: examples/sense_hat_remote_2.py
|
|
|
|
Note that in this case, the Sense HAT code must be run locally, and the GPIO
|
|
remotely.
