Not to ruin the arduino fun, but wouldn't one of the outlet timers(like the kind for christmas lights) be the best bet? It would be way cheaper and accurate.
lol Granted, but that´d ruin the arduino fun. ;D But I want to eventually have the information displayed on a screen (such as the touchshield slide), this way gives me a lot more options, fun, and learning experience. Rather than a christmas lights timer I could go for a DS1037 RTC.
