F.A.Q.
How come 'looping tracks' like TO1LATCH.WAV dont loop in UART mode?
I am having difficultly triggering GPIO #9 and #10
If I hold down a button in 'play once' Tnn.WAV mode, it will repeat!
I don't have short delays between loops, whats up with that?

Overview
Would you like to add audio/sound effects to your next project, without an Arduino+Shield? Or maybe you don't even
know how to use microcontrollers, you just want to make a sound play whenever you press a button. What about
something that has to be small and portable? You are probably feeling a little frustrated: it's been very hard to find a
simple, low cost audio effects trigger that is easy to use and does not require any programming
UNTIL NOW!
Don't get me wrong, I love the MP3 Music Maker shield, and our Wave Shield is a dependable classic. But you still
need to get an Arduino involved. There's all sorts of tricks with ISD chips or recordable greeting cards, but they never
sound any good. So after a lot of engineering and tinkering we've come out with the Adafruit Sound Board, the easiest
way ever to add audio effects to a project!

The Sound Board has a lot of amazing features that make it the easiest thing ever:
No Arduino or other microcontroller required! It is completely stand-alone, just needs a 3 to 5.5VDC battery
Small - only 1.9" x 0.85"
Built in storage - yep! you don't even need an SD card, there's 2MB or 16MB of storage on the board itself, so
