    Alright, well all these names regarding 555 circuits are confusing the hell outta me :confused: What I want to know is this: what type of circuit is it called when you power on a 555, which then waits for ~30 seconds, and once the delay is over, switches to the "high" state. Im talking about the names like astable, monostable, astable multivibrator mode....etc,...what would the above mentioned usage be called???any help, thanks!

    That would be a monostable multivibrator. It only changes states once.

    Two one shots[ monostable ], first for delay, second for positive delayed output. As you do not mention pos. out of falling, it is more like a switch. Or if an RC delay is used; RC delayed switch.
