What you need

• Arduino
• Connection Wires
• Audio MP3 Bluetooth Reader Module
• MP3 Files

Steps

1. 1. Connect the Audio MP3 Bluetooth Reader Module to your Arduino using the connection wires.
2. 2. Break the pins of the module to identify the following connectors: VCC, GND, SDA, SCL, BT_SCK, BT_MISO, BT_MOSI, BT_CS, BT_IRQ.
3. 3. Connect VCC to the 5V of Arduino and GND to the GND of Arduino.
4. 4. Connect SDA and SCL of Arduino to BT_MISO and BT_MOSI respectively.
5. 5. Connect BT_CS to a digital pin of Arduino.
6. 6. Connect BT_IRQ to another digital pin of Arduino.
7. 7. Load the provided Arduino code.
8. 8. Load your MP3 files onto an SD card.
9. 9. Set your smartphone to connect to the Bluetooth audio reader.
10. 10. Try to play an audio file.

Example code

```
#include <MP3Player.h>

MP3Player mp3;

void setup() {
  Serial.begin(9600);
  mp3.begin();
}

void loop() {
  if (Serial.available() > 0) {
    String command = Serial.readString();
    if (command == "play") {
      mp3.playFile("file.mp3");
    }
  }
}
```
