Wave (Sound) Shield for Arduino Kit

Want to add sound to your next Arduino project? Here's the solution, it can play up to 22KHz, 12bit uncompressed audio files of any length. Provided as an easy to solder kit. Audio files are read off an SD/MMC card. Volume is controlled by an onboard thumb-wheel. Produced by adafruit industries.

This shield has its own library (download-able from the link below). To use simply drag uncompressed wave files onto the SD card and plug it in. Then use the library to control when sounds are played (when a button is pressed, a sensor goes off, the possibilities are endless). Audio is played asynchronously as an interrupt, so the Arduino can perform tasks while the audio is playing.

(note: version 1.0 is pictured but we are shipping the new and improved version 1.1 kit)

Features:

• Can play any uncompressed 22KHz, 16bit, 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. Check out the demo video/audio at the webpage
• Included library and examples makes playing audio easy
• Files are read off of a FAT16-formatted SD/MMC card
• 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
• 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 an ATmega168-based Arduino (or compatible) but for more complex projects we strongly recommend upgrading to an ATmega328!
