Hi, I'm creating a plant vase who speaks when you walk in front of it, i'm having problems with the instructions who should make the vase talk.
when i type mp3.play(x) it doesn't produce any sound and when i type mp3.next() it produce a part of the 2 audio track and after a small amount of time it produce a small part of the consecutive audio. i tried to use the example with the DFPlayer mini library but it doesn't work.
any ideas?
Post your code.
In code tags
And your wiring circuit, please.

sorry, i am new on this platform, i'm not allowed to post photos of the content of the SD card or the wirings
i read about other guys having problems with the DFPlayermini, i can garantee i have named every file like this 0001.mp3, 0002.mp3, 0003.mp3 and the SD card has been format in fat32

So you've got a lot going on with the code, and I think that's where your problem lies. Remember that DELAY is a blocking function and stops all commands in the program, so not the best use of it in a program where we want to mix LED lighting and DF Mini Player MP3 sounds. You need to rewrite using Millis timing. Study the Blink Without Delay example to learn.
Also this line:
delay(1);
Delays need to be longer than 1 millisecond.
And:
digitalWrite(3,LOW);
digitalWrite(6,HIGH);
Those two pins are nowhere in your sketch.
