Is there a possibility to play music from Arduino without any shield??
Just only use an sdcard.
Like an mp3 player.

Depends on what's on the SD card and on what quality you expect. If you have MP3s on it or if you expect MP3 quality of it: forget it with an UNO, it may work with a Due.
does it work with the mega?
does it work with the mega?
No, the Mega2560 is identical to the UNO in this regard.
Tell us what you plan to achieve and not how you want to achieve it.
i just want to do a project .i have an arduino uno and a mega.
i'll buy an sdcard and i want to do a simply mp3 player.
From the research that I have done, the Arduino has enough trouble streaming the data from an SD card to an MP3 decoder IC fast enough, so I would say no, it isn't possible to do MP3s because on top of trying to stream the data fast enough, you also have to attempt to do decompression and decoding of the audio, conversion to analog voltages, etc...
I have seen WAV players that with nothing but the arduino and an SD card. Look for WaveHC on the forums here.
ok i find it thanks for your time!
