THANK YOU!!!!

I've been reading tech threads like crazy so I'm starting to pick up this info, but it's super helpful to have it explained clearly in one location!

The animation does show it clearly, but it moves a little fast to register all the info at first. You might want to either break the steps up into separate loops or slow down the loop just a tiny bit. We noobs have to study the image closely to make sure we aren't missing anything on it, lol.

Otherwise, the way you are breaking down the info is very easy to follow. My dad has shown me a little bit about reading schematics, and he never mentioned the part about needing a return path for a circuit to activate. I'm going to go out on a limb here, and guess that I will need to remember that when I get into more complicated circuitry.
