This is the sd card shield which I have bought
rhydoLABZ
Please help me I want to play audio/wav files stored in sd card using this shield and arduino
Depending on the quality you want, it may not be possible.
Assuming you can read the card, how will you get sound from the Arduino? It doesn't have an audio output.
You'd be better off getting a shield which has dedicated audio, eg. this one:SparkFun MP3 Player Shield - DEV-12660 - SparkFun Electronics
