How to read analog signals?

[Archangel]

Hey joe Well this is the thing I want to setup a little project . You may remmeber me from the xbox 360 thread. But i didint get a chance on that. So i wanted to seeif i can acually get to read the trigger press and pulse out.


Also I wanted this to be done on a pic 12f683

Well The reason i want it on the same pin because I dont think i can kill 2 birds with one stone meaning as There is only on spot to read and fire of the controller which is called the wiper. I have seen this done before. So lets say i pull the trigger the pic reads the analog then it pulses low.

I did not forget . . . Here is what I am having trouble understanding "i pull the trigger the pic reads the analog then it pulses low" Exactly what do you mean by "the PIC reads the analog", What exactly must it see, to then make the pic pulse low? What state is the pin in when the condition is NOT met ? What state is it in when you want the pic to fire ?
