Just wondering here, i'm triggering a counter, how do i make a comparator have an adjustable trigger?? add more Res's and Cap's?

Your description is severly lacking in describing what you want to do. But I'll take a stab at reading your mind.

To adjust the threshold voltage in a comparator circuit (trigger?), you can use a voltage divider where one of the resistors is a potentiometer.(adjustable!) that give you an adjustable "trigger" point.

If you provide your schematic, someone can provide a markup of what you need. Otherwise, its just mind reading and describing circuits with english. Good luck.

 

Adjust the reference voltage that you're comparing against.

 

Why not just make an astable multivibrator?
a 555 timer will work nicely as your counter clock.

and nice avatar :wink:
