DFplayer Mini MP3 Player-TF-16P
DFPlayer Mini is a small MP3 player module, ideal for playing music from a MicroSD, it has different control modes, it can operate independently using buttons and a power supply, be used with a female USB Jack and have control through serial communication with its TX and RX pins It is compatible with Arduino development boards or any other microcontroller that has UART ports.
It is used to develop different prototypes that allow audio to be played in MP3 format.
It is used to play audio autonomously with the help of an MCU and create alarm systems to give warnings, against fires, earthquakes and others.
In addition, it has an integrated 3W amplifier to directly connect a speaker.
There is also a headphone and amplifier output.
The module supports MP3 and WMV decoding and sampling rates up to 48 kHz. The SD card supports FAT16, FAT32 up to 32GB with a maximum of 100 folders with every 1000 songs.
The speaker and headphone jacks are connected to a 24-bit DAC with a dynamic range of up to 90dB.

How to connect and program the MP3 player module for Arduino?
In the following tutorial you will learn in a simple way how to connect and program the mini MP3 player with the Arduino uno board, the materials that we will use are the following
Materials
Mini Mp3 Player Module
Arduino Uno
4 long cables MM-MM
3W, 4 Ω or maximum 8 Ω speaker
Mini breadboard 170 pts
1 kΩ resistor
MicroSD memory minimum 2GB maximum 32GB
How to connect the mini mp3 player module to Arduino uno?
We simply power the MP3 player using the 5V supply and GND of the Arduino.
On the other hand, connect the RX and TX pins to pins 11 and 10 of the Arduino.
Finally, connect the speaker to the DFPlayer Mini to the Spk_1 and Spk_2 pins.
In the following image you will have the connection you must make.
How to program the mini MP3 player module with Arduino?
After making the connection we will continue with programming the MP3 player.
To program the module with the Arduino IDE you just have to download the DFRobotDFPlayerMini library and then import it to the Arduino IDE.
Once you have loaded the library, copy the following code and upload it to your Arduino Uno.
Remember that you must have already made the connections previously made. we mentioned.
#include "SoftwareSerial.h"
#include "DFRobotDFPlayerMini.h"

Serial . println (F( "1.Please recheck the connection!" ));
Serial . println (F( "2.Please insert the SD card!" ));
while ( true );
}

myDFPlayer.next(); //Play next mp3 every 3 seconds.
}
