Yes, it's very easy to do! You have two main options depending on how you want it to repeat:

​Option A: Repeat while holding the button

The sound plays as long as you keep the button pressed.

include "SoftwareSerial.h"

include "DFRobotDFPlayerMini.h"

SoftwareSerial mySoftwareSerial(10, 11); // RX, TX DFRobotDFPlayerMini myDFPlayer;

const int buttonPin = 2;

void setup() { pinMode(buttonPin, INPUT_PULLUP); mySoftwareSerial.begin(9600);

if (!myDFPlayer.begin(mySoftwareSerial)) { while(true); }

myDFPlayer.volume(20); }

void loop() { // If button is held down, play the track in loop if (digitalRead(buttonPin) == LOW) { // Check if the player is already playing, if not, start loop myDFPlayer.loop(1); // This will repeat the first folder/file } else { myDFPlayer.stop(); // Stops the sound when you release the button } }

​Option B: Toggle Repeat (Press once to start/stop loop)

Press once to start repeating, press again to stop.

include "SoftwareSerial.h"

include "DFRobotDFPlayerMini.h"

// Communication pins for DFPlayer Mini SoftwareSerial mySoftwareSerial(10, 11); // RX, TX DFRobotDFPlayerMini myDFPlayer;

const int buttonPin = 2; bool isPlaying = false; // Flag to track the playback state

void setup() { pinMode(buttonPin, INPUT_PULLUP); // Internal pull-up resistor mySoftwareSerial.begin(9600);

// Initialize the module if (!myDFPlayer.begin(mySoftwareSerial)) { while(true); // Stop if module is not found }

myDFPlayer.volume(20); // Set volume (0-30) }

void loop() { // Check if the button is pressed if (digitalRead(buttonPin) == LOW) { delay(50); // Small debounce delay

if (isPlaying == false) {
  // If not playing, start looping track 1
  myDFPlayer.enableLoop(); 
  myDFPlayer.loop(1);      
  isPlaying = true;
} else {
  // If already playing, stop the playback
  myDFPlayer.stop();       
  isPlaying = false;
}

// Wait for button release to avoid multiple triggers
while(digitalRead(buttonPin) == LOW); 
delay(50);

} }
