Module for controlling the LED matrix on the SenseHat of a Raspberry Pi.
Module for controlling the LED matrix or reading environment data on the SenseHat of a Raspberry Pi.
:maintainer: Benedikt Werner <1benediktwerner@gmail.com>
You can specify the rotation of the Pi in a pillar.
This is useful if it is used upside down or sideways to correct the orientation of the image being shown.
Example:
.. code-block:: yaml
sensehat:
rotation: 90
