Here is the code i use:

Endd


The audio files that i use is downloaded here: http://www.mp3int.com/search.php
, i have write leo le chat and downloaded the second file which i named 000.mp3 and he is saved on my card on a file named 00.



When i open the serial plotter i read:
send so i write :
1
he answer:
specify the music index
i write:
2
he answer
pause the mp3 player

But there is no sound i don't get the problem.

Thanks by advance

Hi,

Try this solution :

- Go to sketch > include a library > Manage library > instal grove mp3
- Connect the grove mp3 to D18 and 19 if you use an arduino mega + shield, like me


Code: [Select]


#include <MP3Player_KT403A.h>

SoftwareSerial mp3(19,18);

void setup()
{

  // the grove module is configured to talk at 9600 bauds, so this is the speed that we choose
  mp3.begin(9600);

  // small delay to make sure everything starts well
  delay(100);
 
 // We configure the library to use the SD card
  SelectPlayerDevice(0x02);

  // Set the volume to 15, allowable values ​​are 0 to 30
  SetVolume(15);

  // index of the song between 0 and 65535 (unsigned int - uint16_t)
  //WARNING: files are ordered by creation date!
  SpecifyMusicPlay(12);

}

void loop()
{
   
}
