Code:-

#include “SoftwareSerial.h”
#include “DFRobotDFPlayerMini.h”

// Use pins 2 and 3 to communicate with DFPlayer Mini
static const uint8_t PIN_MP3_TX = 26; // Connects to module’s RX
static const uint8_t PIN_MP3_RX = 27; // Connects to module’s TX
SoftwareSerial softwareSerial(PIN_MP3_RX, PIN_MP3_TX);

// Create the Player object
DFRobotDFPlayerMini player;

void setup() {

// Init USB serial port for debugging
Serial.begin(9600);
// Init serial port for DFPlayer Mini
softwareSerial.begin(9600);

// Start communication with DFPlayer Mini
if (player.begin(softwareSerial)) {
Serial.println(“OK”);

// Set volume to maximum (0 to 30).
player.volume(20);
// Play the first MP3 file on the SD card
player.play(1);
} else {
Serial.println(“Connecting to DFPlayer Mini failed!”);
}
}

void loop() {
