VS1053 Shield Power OFF

shallsus23 · December 20, 2025, 8:42am

Hello, Sir.

I am trying to create functions for recording and playing MP3 files. I am using an Arduino Uno with a VS1053 shield. However, when I try to play a recorded MP3 from the SD card using the VS1053 shield, it doesn’t work.

This is my code. *********************************************************

#include <SPI.h>
#include <SdFat.h>
#include <SFEMP3Shield.h>

SdFat sd;
SFEMP3Shield MP3player;

const char* TARGET_FILE = "1.mp3"; 
char actualFileName[13]; // Variables to store file names found in real SD
bool fileFound = false;

byte volumeState = 30;
#define VOLUME_PIN A0

// [Add] A function that lists all the files on the SD card and checks if you have TARGET_FILE
void listAndFindFile() {
  SdFile root;
  SdFile entry;
  root.open("/");

  Serial.println(F("--- [SD Card File List] ---"));
  
  while (entry.openNext(&root, O_RDONLY)) {
    char name[13];
    entry.getName(name, sizeof(name));
    Serial.print(F("File found: ")); 
    Serial.println(name);

    // Find the name
    if (strcasecmp(name, TARGET_FILE) == 0) {
      strcpy(actualFileName, name);
      fileFound = true;
    }
    entry.close();
  }
  
  Serial.println(F("---------------------------"));
  if (fileFound) {
    Serial.print(F("Match Found! Using file: "));
    Serial.println(actualFileName);
  } else {
    Serial.println(F("ERROR: Target file NOT FOUND on SD card."));
  }
  root.close();
}

void setup() {
  Serial.begin(9600);
  while (!Serial);
  Serial.println(F("Initializing SD & MP3 Shield..."));

  // 1. Init SD card
  if (!sd.begin(9, SPI_HALF_SPEED)) {
    Serial.println(F("SD initialization failed!"));
    sd.initErrorPrint();
    while (1);
  }
  Serial.println(F("SD Card OK."));

  // 2. Print File List
  listAndFindFile();

  if (!fileFound) {
    Serial.println(F("Please check your SD card and restart."));
    while (1); // 파일을 못 찾으면 여기서 중단
  }

  // 3. Init MP3 Player
  uint8_t result = MP3player.begin();
  if (result != 0) {
    Serial.print(F("VS1053 Error Code: "));
    Serial.println(result);
    while (1);
  }
  Serial.println(F("VS1053 OK."));

  MP3player.setVolume(volumeState, volumeState);

  // 4. Play with a founded record.
  result = MP3player.playMP3(actualFileName);
  if (result != 0) {
    Serial.print(F("Play Error: "));
    Serial.println(result);
  }
}

void loop() {
  // When the song is over, repeat it
  if (!MP3player.isPlaying()) {
    MP3player.playMP3(actualFileName);
  }

  // Control Volume
  static uint32_t lastVolTime = 0;
  if (millis() - lastVolTime > 200) {
    int potValue = analogRead(VOLUME_PIN);
    byte newVol = map(potValue, 0, 1023, 10, 100);
    
    if (abs(newVol - volumeState) > 2) {
      volumeState = newVol;
      MP3player.setVolume(volumeState, volumeState);
    }
    lastVolTime = millis();
  }
}

This is the result **************************************************

17:19:15.505 -> --- [SD Card File List] ---

17:19:15.537 -> File found: System Volum

17:19:15.569 -> File found: 1.mp3

17:19:15.569 -> File found: 2.mp3

17:19:15.601 -> File found: 3.mp3

17:19:15.633 -> File found: 4.mp3

17:19:15.633 -> ---------------------------

17:19:15.666 -> Match Found! Using file: 1.mp3

17:19:15.881 -> VS1053 Error Code: 6.

I also use SFEMP3SHIELD FilePlayer Example. But it also not working when I choose the mp3. How can I solve this problem.

Please correct your post and add code tags around your code.

There is a small pencil below your existing post.

click on this pencil ➜ that will let you edit your post.

Thank you, sir.

J-M-L · December 20, 2025, 8:46am

can you verify your SPI connections and pins ? (Is the shield correctly plugged in ?)

Can you also try powering the UNO from a 9V DC adapter or USB from your computer and remove the battery pack

b707 · December 20, 2025, 10:44am

The errorcode 6 means that you didn't load .plugins files to your SdCard as described in

For more info see the "installation" and " Plug Ins and Patches" sections of the guide.

lichurbagan · December 20, 2025, 11:05am

This error means that the shield cannot read the SD card. VS1053 MP3 Shield Not Reading SD Card

b707 · December 20, 2025, 11:08am

Is not the case. The output of the code shows a list of the files, so that there are no problem with SD reading.

Take note, that OP used a SFEMP3Shield class in his code. It has a different errorcodes. See the source

J-M-L · December 20, 2025, 11:38am

is your VS1053 shield a clone or an original SparkFun MP3 Player Shield or Seeduino MP3 Player Shield ?

@shallsus23 I have a shield that looks like yours in every way and I once used it with the Adafruit library. The Adafruit library example was written for their VS1053 breakout module and I reassigned the pins to match the Arduino UNO.

If you try this use a SD card of 32GB or less and remove the large capacitor and battery pack, at least until you know it works. I have not used this for a long time but it appears I used filenames like 001.mp3 , 002.mp3 etc.
