Hey I'm trying to figure out how this LED works. I know how to hook it up but I'm wondering whether the colors are controlled by voltage change or what have you. If not, is there a type of LED that changes color based on voltage or current manipulation because that is what I'm looking for. Here is the part from radio shack...but it will most likely break in a day because it is from radio shack.
