In the future try to respond under the assumption that the person you are speaking to has some knowledge and has done a little research. You will come off as a much nicer and considerate person that way.
No disrespect meant or given. Nothing in your original post suggested your hands on experience working with AC power nor even your age for that matter, just your goals. We have a running topic around here somewhere where we discuss how much help we should give to new posters asking for help interfacing with AC power, or if we should offer any help at all. There is a school of thought of "if you have to ask, then you shouldn't mess with it", and I tend to bend to that side of the issure. Often these are minors with giant ideas but little experience. It's not a black and white issue, trust me. My suggestion to 'play safe' with AC power is a good reminder to anyone, because it is given with good intentions, believe me. I worked in a oil refinery for 27 years before retirement and I saw first hand some very serious injures to experience trained journeymen level electricians, it wasn't a pretty site.

That is the root of the problem. If we are to always assume competency in electronic and power safety from every poster asking for help, advice, or suggestions on working with AC power, it brings back the issues I just discussed. We get so many new members of all ages and experience levels here, it really is a active forum. So do you at least see my side of the discussion? I belive there is pretty high level of mutual respect shown on this forum, much more then many others I have visited. You will seldom see any flaming threads around here, It's really a pretty friendly forum.
Look forward to any contribution you can add to the Arduino world.
