Can't Use DFPlayer Mini Player Sensor on Arduino Uno

Hello Everyone
I want to use dfmini player to play Songs on the arduino and output it on a 8 ohm 0.5W Speaker , and nothing is working .I am using the DFRobotDFPlayerMini Library code as is but nothing is playing at all .Attached is Photo of a similar connection like mine and i didnt use a breadboard as actually the DF Player is slightly bigger than the holes. The Arduino Pins Used is 11,10 and 5V and 2 Pins for the GND Here is the Code of the DFRobot Library used as is . The Files on the SD Card are in a folder mp3 and written as 0001.mp3 0002.mp3 ..etc When i Connect and try it out . The Blue Led on MP3 Player doesn't light up , and on the
Serial Monitor Baud 115200 :
DFRobot DFPlayer Mini
DFRobot DFPlayer Mini Demo
Initializing DFPlayer ... (May take 3~5 seconds)
DFPlayer Mini online
. and on Serial Monitor Baud 9600:
⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮ܙf⸮⸮⸮⸮⸮⸮⸮⸮
When I make all serial (9600) , the Question Marks are not printed
Would be very thankful if anyone can solve this problem.
Here is Link of connection in the website i made: The Black Photo

Note : i have seen alot of forms but none of them worked for me

Here is Also the Code Used

#include "Arduino.h"
#include "SoftwareSerial.h"
#include "DFRobotDFPlayerMini.h"

SoftwareSerial mySoftwareSerial(10, 11); // RX, TX
DFRobotDFPlayerMini myDFPlayer;
void printDetail(uint8_t type, int value);

void setup()
{
  mySoftwareSerial.begin(9600);
  Serial.begin(115200);
  
  Serial.println();
  Serial.println(F("DFRobot DFPlayer Mini Demo"));
  Serial.println(F("Initializing DFPlayer ... (May take 3~5 seconds)"));
  
  if (!myDFPlayer.begin(mySoftwareSerial, false)) {  //Use softwareSerial to communicate with mp3.
    Serial.println(F("Unable to begin:"));
    Serial.println(F("1.Please recheck the connection!"));
    Serial.println(F("2.Please insert the SD card!"));
    while(true){
      delay(0); // Code to compatible with ESP8266 watch dog.
    }
  }
  Serial.println(F("DFPlayer Mini online."));
  
  myDFPlayer.volume(10);  //Set volume value. From 0 to 30
  myDFPlayer.play(1);  //Play the first mp3
}

void loop()
{
  static unsigned long timer = millis();
  
  if (millis() - timer > 3000) {
    timer = millis();
    myDFPlayer.next();  //Play next mp3 every 3 second.
  }
  
  if (myDFPlayer.available()) {
    printDetail(myDFPlayer.readType(), myDFPlayer.read()); //Print the detail message from DFPlayer to handle different errors and states.
  }
}

Please go to Libraries and download DFMiniFast to use as your library. This has come up in the Audio section quite a bit and I think there might be something odd with the Play command in the normal DFPlayerMini Library. Use the Example code and let us know what happens when you try that. Also, is it a genuine DF Mini or a knockoff from Ebay or AliExpress? Lastly are you powering the Arduino from the USB cable right now?

Hi ,
I will use the DFMiniFast as you have suggested and will tell you what i got .I believe it is the genuine one . Also , i am powering and testing the Module on the Arduino Using the USB Cable .Is this a problem ? Another Question : Is Pin 11 and 10 Used , are they correct ? Cause on the Arduino Board TX and RX printed on Pin 0 and Pin 1 ?and in some Videos on Youtube , they use Pin 2 and 3?
Thank you for your help

Powering the Arduino by USB Cable is fine- just wanted to make sure of the power source you are using. Pins 10/11 for RX/TX are the way to go as most example codes are used for those pins.

Well ,i have downloaded the library ,The Blue Led of the module still didnt light up .When i Upload the serial monitor gives ⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮~)⸮! .However when i make the Serial .begin (9600) instead of 115200 it prints
Setting volume to max
Sent Stack:
7E FF 6 6 0 0 1E FE D7 EF

Looping track 1
Sent Stack:
7E FF 6 8 0 0 1 FE F2 EF

So what is still the problem ?
The Code is Here :
{

#include <DFPlayerMini_Fast.h>

#if !defined(UBRR1H)
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX
#endif

DFPlayerMini_Fast myMP3;

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

#if !defined(UBRR1H)
  mySerial.begin(9600);
  myMP3.begin(mySerial, true);
#else
  Serial1.begin(9600);
  myMP3.begin(Serial1, true);
#endif
  
  delay(1000);
  
  Serial.println("Setting volume to max");
  myMP3.volume(30);
  
  Serial.println("Looping track 1");
  myMP3.loop(1);
}

void loop()
{
  //do nothing
}

}

Ok, we know the Arduino is communicating with the DF Mini, so that's good. Now let's ASSUME its a power issue where the LED isn't lighting up. Can you check the 5V line to the Power Pin on the top of the DF Mini and the ground to the DF Mini (that one gets a little tricky as its located between the 2 Speaker + and - pins). If you are using Dupont wires make sure they are tight.

I don' t see your photo, just the crappy fritzing thing.

Which Arduino are you using?

Has the library changed?
It used to be 100 folders and 255 files per folder

Jumping ahead a little here @kareemafifi but if you feel its wired correctly can you try this example please?

#include <SoftwareSerial.h>
#include <DFPlayerMini_Fast.h>

SoftwareSerial mySerial(10, 11); // RX, TX
DFPlayerMini_Fast myMP3;

void setup()
{
  Serial.begin(115200);
  mySerial.begin(9600);

  myMP3.begin(mySerial);
  
  Serial.println("Setting volume to max");
  myMP3.volume(30);
  delay(20);
  
  Serial.println("Playing track 1 for 5 sec");
  myMP3.play(1);
  delay(5000);

  Serial.println("Sleeping for 5 sec");
  myMP3.sleep();
  delay(5000);

  Serial.println("Waking up");
  myMP3.wakeUp();

  Serial.println("Looping track 1");
  myMP3.loop(1);
}

void loop()
{
  //do nothing
}

Its the older DFMiniFast Example- I just wanted to see if it makes a difference from the upgraded version.

Yes, i am using Dupont Wires , and i made sure everything is fine . Where do think is the problem ? i am also connecting 2 GNDs to the Module if you see the schematic There is one on the left and one on the right

I am using arduino Uno . On the SD Card , There is a folder named mp3 and in this folder there is 0001.mp3,0002.mp3 0003.mp3,0004.mp3

But if the player is looking for tracks numbered 0...255, aren't those files all going to look the same?

The Blue Led is still not lit . The Serial Monitor Prints
Setting volume to max
Playing track 1 for 5 sec
Sleeping for 5 sec
Waking up
Looping track 1

So What do you suggest ?

More obviously unique filenames

Woah. Hold on. You only need to wire the left side of the DF Mini player. Ignore what is on the Right side per your schematic you have posted. Any chance you can post a photo of your wiring by a photo, can we see it?

Schematic?
Have I missed something?

The fritzing diagram he posted.

There is nothing on the right hand side

I know that this is not the best image
I know there is No GND on the right Side , but thought that this the problem but still it didnt solve the issue

OK- everything on the wiring looks good- the resistor is a little wonky with the 2 male dupont wires but we know the Arduino is communicating. My gut tells me that's a knockoff DFMiniplayer that needs more voltage than the 5v the Arduino can supply. Where did you buy the DFMini from? Do you have a seperate power supply that you can power the DFMini from without going through the Arduino Uno board?
