Working with the waveshield.
I'm having a lot of trouble with this, not going to lie. I'm looking at all of these websites:

https://learn.adafruit.com/adafruit-wave-shield-audio-shield-for-arduino/wavehc-library
http://www.circuitdiagram.org/sound-to-light-led-project.html
and I've downloaded all of the appropriate libraries that I need but the basic code that just lets me know if the wave shield is working okay isn't working at all. I don't know if the libraries aren't up-to-date or what but I'm a little concerned. I've looked at both Matt's and Claire's projects/codes and even though it doesn't seem like anyone has connected a sound sensor to a wave shield, I think I can work with what they have and tweak it to fit my needs. This is what I have so far:

#include "WaveUtil.h"
#include "WaveHC.h"
SdReader card; // This object holds the information for the card
FatVolume vol; // This holds the information for the partition on the card
FatReader root; // This holds the information for the filesystem on the card
FatReader f; // This holds the information for the file we're play
WaveHC wave; // This is the only wave (audio) object, since we will only play one at a time
//*************THINGS DECLARED*************************

}
It certainly needs some more work but I can't even test it because I can't seem to get the wave shield to respond, even though all of the .wav files are perfectly on there. I don't really know what to do. It's the day before this project is due but I'm going to give it a couple more tries. At 8pm tonight if I still can't get it to work then I might have to figure something else out L O L .............
