I don't actually get my Arduino until Monday, but I'm ready to hit the ground running the second I do. I wired up the solid state relays and the high voltage side of things today. I have a bunch of pictures here:

It's not going to be anything crazy, no dancing to music or anything. Simply the ability to have a couple different patterns.. I'll have some video by Tuesday.

For the relays, I used 8 of these. They are solid state relays, good for about 100watts AC. They're nice and high impedance, and draw about 17ma, so I can run them directly off the CPU pins of the Arduino with no extra circuitry.

I can't see it on the picture, but do they have an internal diode, or did you put one on? There must be one to prevent the coil from slapping the arduino back.

They are solid state relays, meaning no coil. No need for a flyback diode.

LOL you are right, didn't see that in the text.

I had a bug in one of the modes (patterns) in the sketch I had on the Arduino when I shot the video, that's why it freezes at one point in the video. It's all better now.
I love this Arduino! :)
