555

hey im new to electronics I have made some basic led flashers with a 555 but I would like to know some more

Well, it's a very simple and very cheap timing circuit that can be adapted for a lot of potential uses, there are entire books written about it.  It can be used for a simple low-speed clock for other clocked digital circuits, LED flashers, tone generators, it can be a non-retriggerable one-shot, which means after some event happens it sends out a pulse of a certain length, this can be used for timing actions, and it can be bi-stable too, though this has always seemed less useful to me.

Looks like some good free information here:  http://www.555-timer-circuits.com/

The Talking Electronics website has a bunch of 555 circuits as well as an explanation of how the 555 IC works.

Download and read the datasheet as well.
