thank you both
In my short time "playing" with the PIC I have not tried any of the adc stuff
the 16f676 is the sister chip to the 630 about the same but with adc
is this the way I need to go?

the 100 scale well I worked for 6 hr. before I got some thing that would work
(on the other project) started with 255 but did not have any luck ajusted both # and until 100 and it worked.
