ADAFRUIT WAVE SHIELD FOR ARDUINO KIT - V1.1

ADAFRUIT WAVE SHIELD FOR ARDUINO KIT - V1.1

Adding quality audio to an electronic project is surprisingly difficult. Here is a shield for Arduino 328's that solves
this problem. It can play up to 22KHz 12bit uncompressed audio files of any length. It's low cost, available as an
easy-to-make kit. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an
SD/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel
potentiometer.

This shield is a kit, and comes with all parts you need to build it.

Arduino, SD card, tools, speaker and headphones are not included. It is fairly easy to construct and anyone
with a successful soldering project under their belt should be able to build it.

The shield comes with an Arduino library for easy use; simply drag uncompressed wave files onto the SD card
and plug it in. Then use the library to play audio when buttons are pressed, or when a sensor goes off, or when
serial data is received, etc. Audio is played asynchronously as an interrupt, so the Arduino can perform tasks
while the audio is playing.

• Can play any uncompressed 22KHz 16bit (on a 12bit DAC), mono Wave (.wav) files of any size. While it
  isnt CD quality, it is certainly good enough to play music, have spoken word, or audio effects. 
• Output is mono, into L and R channels, standard 3.5mm headphone jack and a connection for a speaker
  that is switched on when the headphones are unplugged
• Files are read off of a FAT16/FAT32-formatted SD/MMC card
• Included library and examples makes playing audio easy
• Please note that the library is rather bulky, requiring 10K of flash and more than 1/2 K of RAM for
  buffering audio. It works fine using any ATmega328-based Arduino (Duemilanove, Uno or compatible).
• This shield is not Zero, Due, Mega or Leonardo compatible! (Only for use with '328-based Arduinos)
