MP3 Player Shield

Plays MP3 and other audio files from a microSD card, with hardware decoding so the Arduino only has to send commands, not process audio. Provides a headphone or line-level output for connection to an amplifier or powered speakers. Common in talking exhibits, alarm systems, museum installations and any project that needs real recorded sound instead of a buzzer's beeping. Hardware audio decoding leaves the Arduino free; Plays files directly from a microSD card; Headphone and line-level output; Volume and track control from your sketch
