Adding quality audio to an electronic project is no longer considered treacherous territory best left to the experts, thanks to the Audio Player WaveShield Kit. This clever shield board can play up to 22kHz, 12-bit uncompressed audio files of any length. A great low-cost, easy-to-make kit. (Previously called the Waveshield)
Adding quality audio to an electronic project is surprisingly difficult. The Audio Player Shield is a shield for Arduinos that solves this problem. It can play up to 22kHz, 12-bit uncompressed audio files of any length. A great low-cost, easy-to-make kit. It has an onboard DAC, filter, and op-amp for high-quality output. Audio files are read off an SD/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel potentiometer.
The Audio Player 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 Audio Player Shield comes with an Arduino library for easy use; simply drag uncompressed WAV 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.
