Input Devices
|
|
=============
|
|
|
|
.. currentmodule:: gpiozero
|
|
|
|
These input device component interfaces have been provided for simple use of
|
|
everyday components. Components must be wired up correctly before use in code.
|
|
|
|
.. note::
|
|
|
|
All GPIO pin numbers use Broadcom (BCM) numbering. See the :doc:`recipes`
|
|
page for more information.

Base Classes
|
|
============
|
|
|
|
The classes in the sections above are derived from a series of base classes,
|
|
some of which are effectively abstract. The classes form the (partial)
|
|
hierarchy displayed in the graph below:
|
|
|
|
.. image:: images/input_device_hierarchy.*
|
|
|
|
The following sections document these base classes for advanced users that wish
|
|
to construct classes for their own devices.
