Audio player using VS1003, SD card and Arduino Mega, Circuit and program

After completing the circuit, upload the following program to Arduino Mega. Program tested and worked good on Arduino 1.8.10. Change the value of “audioName” to the name of audio file to be played in the SD card. Audio files should be stored in the SD card as shown in the following image.

#include <SPI.h#include <SD.h// SCI Registers

const uint8_t SCI_MODE = 0x0;
const uint8_t SCI_STATUS = 0x1;
const uint8_t SCI_BASS = 0x2;

VS1003 voice recording and storing in SD card for indefinite time using Arduino Mega, Circuit and program

Upload the following program to Arduino Mega. Open the serial monitor. Now, press the push button switch provided in the circuit. Recording will start and stop in alternate presses of push button switch. Once recording started, press the push button switch again to stop recording. Speak something through the MIC. Voice will be recorded in SD card as “wavFile6.WAV”. Take the SD card from the card reader and play the recorded file on computer.

#include <SPI.h#include <SD.h//#include “SdFat.h”
//SdFat SD;

Display “HEX” data of audio “WAV” file from SD card using Arduino Mega

After completing the circuit, upload the following program to your Arduino Mega. A file named “wavFile6.WAV” should be there in your SD card.

//#include <VS1003ESP12.h//#include <ESP8266WiFi.h#include <SPI.h#include <SD.hconst int xcsPin = A3;
const int sdCs = 10;

File myFile;
char fileName[] = “wavFile6.WAV”;
byte data[4];

void disableVS1003(void)
{
digitalWrite(xcsPin, HIGH);
}

void setup () {

pinMode(sdCs, OUTPUT);
// digitalWrite(sdCs, HIGH);

// initiate SPI
SPI.begin();

// initiate a serial port at 57600
Serial.begin(115200);
