This week for homework in pcomp(physical computing) I had to create circuits that were powered by 12v converter. Then the 12 volts were then turned into 5 volts by a 7805 5v regulator. So far I have had no problems with any of labs, that is, until this one.
I can now honestly say I blew several LEDs and caused smoke to rise from them and I managed to destroy 3 voltage regulators. I also had the disadvantage of working on this lab without the diagrams on the server, due to it being offline.
However, I was able to understand the principles of measuring current and voltage, and working with a powersource other than the Arduino.
Here is a video of a simple circuit that I made.

Cool, I have burned a few led's in my time as well *blush* but that is all part of the learning process. I am surprised that you haven't mounted that button in a project box with the wires hanging out so it can be used with the proto board. That way all you have to do is just push the button, not stabilize it as well. You should be able to get a project box at Radio Shack. Do they even have those in NY? I know that sounds stupid, but it is an honest question. If not, I can send a few for you :)
