Hello Arch!,
I was considering the POT command, but the way the info reads is that you would have to calibrate it for each setup to allow for differences in caps and resistors. Is that correct? Since I'll be making several boards, I would have to allow for that so that all components would be the same. Haven't played with the POT command yet, so I don't know how "sensitive" it is, but maybe the thing to do would be to change it until the maximum resistance reads about 125? Then if you have a cap that is off by a large margin, it would still work? Say if a value of 50 or so was enough to know it's dark, then I could just say anything greater than 50 is dark. Does this make sense?
