Okay, Sam, here's a program for you to work with.  Now... let me make it very clear that this isn't ready to run, and that you're going to have to do some tweaking to get it working correctly.  The first step is to build the light detector and them measure daylight levels at several point during the day -- especially near sunrise and sunset -- so that you can set the daylight threshold.

This operates as a state machine.  The main loop has a ~one minute delay which is followed by a sensor measurement.  Then BRANCH is used to jump to one of three sections based on the current state.  The way I see it the program states are: 0) measuring the number of daylight minutes, 1) running the relay, and 2) waiting for daylight to return.

This is a moderately sophisticated program and I urge you to simply study it for a few days before you attempt to use or modify it.  My book, StampWorks (you can get the PDF from Parallax), will be helpful in understanding PBASIC 2.5 -- if you haven't read it you really should.
