Well aside from frying my finger with the soldering iron, almost electrocuting myself, and trying to cut my finger off, today went really well. After wiring the chip up initially with spare wires, I decided it would be a good idea to get to radio shack and wire them up with a wire kit to make it neater to work with. I encountered many problems today. I should say first that the digital voice recorders that we are using have a 5 volt offset voltage so when I don't capacitively couple them that is what makes the noise I referenced earlier. The good news to this is that with Tom's assistance, I figured out how to wire the amplifier up. The bad news is that the original board that the voice recorders were on no longer works so Ann and I "quickly" wired the voice recorders up on a bread board enabling only the extended play option. Thirdly, because of this extended wiring, we have not had any time to go through and troubleshoot the program so I am planning on going in tomorrow to try and make sure we have working code (crossing fingers). Finally, the values I am getting off the photo resistors is inconsistent with what I expected so I will be looking for a little help with that tomorrow.
