  added warning to take off headphones when changing modes
  suggestion: should we add a diagram of the Tympan + Teensy system to just above the Hardware section?

  In the Arduino IDE, under the "File" menu, select "Examples". Then, scroll way to the bottom of the list. You should see an entry that says "Tympan_Library". Those are all the example files for trying out different audio algorithms or features of the system. I recommend starting with the basic examples:
  -* **Audio Pass-Thru:** You should start with this example. No processing, just an audio pass-thru from input (microphone) to output (headset or earbuds). You should always start as simple as possible. It doesn't get simpler than this. Since it doesn't apply any gain, it'll be quiet.

  Once the basic audio pass-thru program works, you can try the next example:
