Gyroscope
============

The gyroscope measures the rate of rotation around a device's x, y,
and z axis.

The :class:`Gyroscope` provides access to public methods to
use gyroscope of your device.

Simple Examples
---------------

To enable gyroscope::

    >>> from plyer import gyroscope
    >>> gyroscope.enable()

To disable gyroscope::

    >>> gyroscope.disable()

To get the rate of rotation along the three axes::

    >>> gyroscope.rotation
    (-0.0034587313421070576, -0.0073830625042319298, 0.0046892408281564713)

To get the uncalibrated rate of rotation along the three axes along with the
drift compensation::

    >>> gyroscope.rotation_uncalib
    ()
    where the first three values show the rate of rotation w/o drift
    compensation and the last three show the estimated drift along the three
    axes.

Supported Platforms
-------------------
Android, iOS
