Finally, I was able to upload a code from this recourse:
http://maxoffsky.com/maxoffsky-blog/how-to-play-wav-audio-files-with-arduino-uno-and-microsd-card/
and connect it to arduino with micro sd card shield(lcsoft.net SD module card shield). Card shield is connected and talking to the arduino. Reading and writing files.
I tried to upload a .wav sample but it sound bad. Looks like we can play just 8bits 14Khz mono sounds.
Problem: Is there any way we can play better sound samples? Is it problem with speaker or library?
