NOTE: THE FIRST THREE STEPS ARE AN INTRO.THOSE OF YOU WHO ALREADY KNOW ABOUT LED's SHOULD SKIP TO STEPS 4 AND 5 FOR THE TIPS. I've been noticing that a lot of people (not people on instructables, but people interested in electronics in general) don't really know about LED's. No one in my science class at school had ever even heard of them. This is an easy introduction to LED's that should teach you the basics. It's good if you're interested but have no idea where to start. I also thought this would help out anyone wanting to enter the contest, but it took me a while to finish. Remember, (As always) feedback and ratings (positive or negative) are always appreciated! FOR MORE INFORMATION SPECIFIC TO WIRING, YOU CAN SEE NOAHW'S INSTRUCTABLE LEDs FOR BEGINNERS""
