Step 2
Once you have all your parts i started out by testing one relay on a bread board
1. Put all the components in acourding to the scematic (image 1)
2. Open the arduino program and goto open>digital>Blink
3. Upload it to your arduino
4. Connect where it says arduino pin on the schematic to digital pin 13
if all works well then its time to multiply that by 8 on a pcb

Beyond the arduino outputs, everything should be the same as dany's setup. Then your songs/light shows are only limited to your patience with the sequencer.
Unfortunately, like you, I am still in the production phase and don't have a finished product to show such as dany's. I am as far as running some test LEDs with the sequence on a bread board, so theoretically, I'll build the board with the relays and be good to go...

I like your idea about the xbee and the climate controlled box. However, part of the deal in getting my wife on board with turning our house into a musical light show involved committing to a budget of practically $0, so I'm working with only components that I already have. But thanks for the tip about the temp of the arduino. I realized that my crawlspace door in the floor of my guest room closet is within a few feet from the nearest crawlspace vent to the front yard. I think I'll set up the whole operation in my climate controlled ;-) guest room, and run the cables beyond the relay through the crawlspace to the front yard.
I also plan on using an FM transmitter to play my music. A buddy that's helping me with some of the wiring work told me that the range of the common dashboard mp3 player transmitters can be boosted by simply soldering a longer wire to their antenna on the cb and coiling around a rod. I guess we'll see if that actually works or not.
Let me know if you can't find the vixen plug-in code for the arduino, and good luck to you too!
