A friend suggested I work on the lighting a bit. Here is what resulted.
[Here is a direct link if the embedded video doesn't show up.]
The Arduino can now control the overhead light with a relay (video here). There are lights in the house and on the end of the loading shed and mill. The star of the show is Ken Stapleton's "Fire" circuit which flickers both a blue LED in the house to simulate TV and yellow LED in a burn barrel.
I also added some nightime audio which plays when the overhead light goes off. The frogs are from a pond near my house, and the dog barking is Mitsty the Wonder Dog, who will bark on command if food is involved.
