The firmware for the alarmclock is implemented in python. The main program
is the script /usr/local/sbin/nerd-colors.py, which is started by
the systemd-service defined in /etc/systemd/system/nerd-colors.service.
The main script does not contain much logic. It mainly creates and loads
various object taking care of the hardware. All classes are submodules
of the ncolors-module. During installation, the code is copied to
/usr/local/lib/python2.7/site-packages/ncolors.
Logically, the software follows the MVC paradigm.
The model is implemented in the class Settings. The LedController is the view,
and the WebThread is the controllers.
Objects don't call methods directly, they only change attributes in
the Settings. They also register callbacks for attribut-changes
there and are called when the registered attribute changes.
