sayzer its was a 16-33k digi-key pvd-p8103-nd this was from a project that I did last year with a 12f629. the PBP manuel says to use a 5-50k &.1cap this had the greatest span and along with a 5k cal pot was still under the 50k as per the manuel. it worked but the pot had little effect. I just added this to the schematic I posted. which is the new project. this is the code I used with the 12f629.

Pot GPIO.4,100,DN
IF DN<140 Then
GoTo CHECKPIR
Else
GoTo MOVIE
EndIF
but If I can get a a greater span from the pot this project can be used for multiple things
thanks
