Thanks for the link! I guess I can just order the "kit" that is mentioned in the guide?
I would prefer having a single LED that switches between green / red. As far as a button goes, something the size of an M&M candy would be perfect.
Maybe just order the parts you want, from any number of sources, or go to radio shack.
If you need a lot more help, just send me a private message.
Is this for fun or a school project?
