I can't get my Arduino to go to sleep. I have tried several examples from the web. This one seems simple enough that I understand it, but it doesn't work either. I have tried two boards, a Pro Mini and a Duemilanove and they behave the same so I don't think it is a hardware fault. Can anyone see wha…
