// Define USE_PHOTOTRANSISTOR as non-zero to use a phototransistor for dark
// detection.  The photocell is connected between the reset/ADC0 pin and
// ground. The pull-up resistor on the /RESET pin is only enabled if the
// RSTDISBL fuse is not set, so defining USE_PHOTOTRANSISTOR as 1 will
// represent a continuous load of up to due to the (approximately 60K) pull-up
// resistor on that pin.
// But the load is still minimal: 25uA or so at 1.5V (at which the part will
// be held in reset anyway). That would be over a year of operation on a
// 240mAH CR2032 cell.
