You're welcome...Now, if you guys inspire ME so much as to pull me off my Arduino etc and back into PICs, I'll be very pssed off - and probably extremely thankful.
They have the same function but act differently. The LDR is a little too sensitive for instantaneous fading (ie If you placed the LDR somewhere by the front windshield, everytime you use your wipers, the screen would dim) but a pot is slightly more stable when it's not being moved (maybe a cap could be used to smooth it out? ).LDRs and pots - same thing aren't they? (Ah ha! Establish a preferred PCB layout or resistance range to accommodate both?
