Pudding it together:
Place wave shield on Arduino. Wire up the photocell on a separate board as per the tutorial. We're going to read the results between a pull-down resistor and 5volt. Cram it in a case. I'm stuck in a hotel with little money or resources. But I still found a Project Case. @Engineers who make amazing things and leave wires everywhere-try putting it in a case, ur wires are lame. Test it out, and mess with your room-mates. They'll be shocked when the British lady in the fridge starts calling them out on their idiosyncrasies. I know rudeness doesn't exactly fit into the Instructables paradigm but no one will actually see this unless it gets featured. So whatevs man. All the really offensive stuff I left for the last page.
I hate when people just attach their code, it always tries to download as a .tmp file and that just seem sketchy to me. Too many smart people on this site to be downloading random files.
