Photo-resister + Arduino/Wave Shield

At last, the audio component of the model is working with the photo-resister sensors. It took 7 iterations of code and many wiring tests to get to this point. Fortunately, I found a solution on the Arduino Forum. The user made use of the example code from Adafruit, where buttons were used to select specific audio files. They then modified it, so that the button input was taken from the photo-resister instead. After a bit of tweaking, the model works. Next step is to put the sensors into the 3D printed model.
