SCENE LEDS
----------
Each SCENE LED *MUST* have a 220 Ohm minimum resistor in series with it. 
The original design only allows for the light behind the exit, but you can also put some lights in the top to light up the trapdoor.


DFPlayer and MP3 Files
----------------------
The SD card needs to be formatted as FAT32, and the files in the MP3 folder need copying on in the order listed or the wrong sounds will play.

Calibration
-----------
To calibrate the system, first follow the steps in the Arduino code for POLARITY 
Once that is correct, follow the steps for DEBUG - See video for details
