 I am currently working on an initial prototype of the dawn light functionality, the following features are intended in this version:

 # Instant dawn/dusk (switches the light on/off over a period of ~30 minutes)
 # Adjustable brightness via a potentiometer (sets the current brightness in mode 3; sets the maximum brightness in modes 1, 2, and 4)
-The prototype will use an incandescent light bulb and Arduino, with the lamp controlled by a optocoupler TRIAC driver - while this may not be the best solution for a final version, it is sufficient to allow a small number of units to be produced.

-* 100 ohm resistor
-* 150 ohm resistor
-Although an Arduino is used in the prototype, it is imagined that this would be replaced with a proper control PCB in a final version.
