Serial mp3 player yx5300

Hello I am trying to use a code that plays a mp3 file from a random list that i found which is working but would like to turn on the led on pin 13 when a file is playing and off when it is not and I'm not sure sure how to. This is going to be used for a halloween prop. Here's My Code any help appreciated.

#include <SoftwareSerial.h>

#define ARDUINO_RX 10  //should connect to TX of the Serial MP3 Player module
#define ARDUINO_TX 11  //connect to RX of the module

#define trigPin 13  //for the distance module
#define echoPin 12

switch the LED on when you start your track.

switch the LED off, when you have received a character on Serial

I am really Bad at code and really don't know how to.

Then you should work with some examples from the Arduino IDE, mainly in the folders "basic" and "digital" and learn how to code.

This might help:

I'm not sure what the feed back is on serial for when a track is done playing i can get the led on by digitalWrite (High) if i put the code line in the loop, but my serial monitor only tells me when its playing. I don't know if theres a way to read RX when its receiving data or when its done receiving data the player

6

based on that example just check in loop if something is in:

```
  if (Serial.available() > 0) {
    // read the incoming byte:
    int incomingByte = Serial.read();

    // say what you got:
    Serial.print("I received: ");
    Serial.println(incomingByte, HEX);
    // and now switch off
   digitalWrite(whateverPin, LOW);
  }

You should read library documentation, I have a feeling it has functions for processing feedback like DFPlayer, if not then find another library or data sheet for the chip. If you just copy pasted the code and know nothing about programming, then wait if someone else with the same board decides to share the solution

What's wrong with the LED on the player?
(My player has one.)
