mv TMRpcm-master/ TMRpcm

Edit

cd ~/Arduino/libraries/TMRpcm
vi pcmConfig.h

Pastikan,

#define DISABLE_SPEAKER2

Code

#include "SD.h"
#define SD_ChipSelectPin 4
#include "TMRpcm.h"
#include "SPI.h"

TMRpcm tmrpcm;

void setup(){
tmrpcm.speakerPin = 9;
Serial.begin(9600);
if (!SD.begin(SD_ChipSelectPin)) {
  Serial.println("SD fail");
  return;
  }

tmrpcm.quality(1);
tmrpcm.setVolume(2);
tmrpcm.play("morat.wav");
}

void loop(){ 
  if( tmrpcm.isPlaying()==1 ) Serial.println("is playing");
  }
