These things do happen... main thing is that it works now! I must say, the schematic is not real clear about the LDR. I'm used to seeing a Page 2 on Ian's other schematics that shows the LDR and the rest of the :front panel devices". Not so with this one. But I recognized the 10K pullup R15, and the inversion of A0 (Line 21 of LDRManager.cpp), from his other designs.
Look into it later when the dust is clearing off the crater.
