Tom, I REALLY appreciate your input here. Your code corrections helped!
I am powering the Adruino board through a 12v power supply because this will be an outdoor decoration. The issue I run into now is if I unplug power and then restore it (simulating a power outage or accidental unplugging), the audio file plays constantly until the LDR senses darkness and the motion sensor is tripped. Then it falls back into proper operation.
I assumed that if power was lost, upon power being restored, the board would go back to the very beginning and run everything from the start of the code.
