Yea, I had no idea what those were really called. I've been building custom computers for years, but just got my first Adruino kit last week. I have a lot of things to learn with it.
I have a few books, so I'm hoping that will help me learn what everything does. I've only got the first project done on the Adruino kit so far, but I'm sure once I get through that book, I'll have a lot more knowledge.
It's nice to know about that website because it looks like they'll have a lot of the things I need. I've been using Amazon and FrozenCPU to get all of my pins/connectors, but Amazon isn't specialized enough, and FrozenCPU is more for computers and ATX/molex connectors and pins.
I'm glad I have a new resource to buy from.
