I think I'm retarded or something.. I do NOT understand buttons whatsoever. Alien_X tried to explain it to me and I just went . I guess I just don't get what the extra points related to a button on a controller do. Like on a gameboy or something, there are like tp1,tp2,tp3, etc. And those are usually related to a button. But then how is it related to a button, and how could I use it for like, leds/external controller/etc? I'm confused.
Oh that makes some more sense, thanks. But then why do some points have voltage coming off them if they're ground?
Like Jumbo said that the two points under a button pad are both grounds, that when completed, complete a circuit.
