+AnalogInterrupt

+ 
+ The circuit:
+ * Three analog comparators
+ * photoresistor from comparator + inputs to +3.3V
+ * 10K resistor from comparator + inputs to ground
+ * Four resistors (1K or more) in series from ground to +3.3V
+ * Junction of each resistor to a single comparator - input
+ * Outputs of comparators to digital pins D2, D3, D4
