In case you want to be able to control the MP3 player from a distance then you may need another way other than using push buttons. Faraday Member; Posts: 3,278; Karma: 452 ; Re: MP3 Players LCD display using with arduino ? There are six functions namely; pause and play, next song, previous song, volume increase , volume decrease and sound equalizer (Normal/Pop/Rock/Jazz/Classic/Base). Both the MP3 module and SD card work with 3.3 V, making it necessary adjust the levels to make them compatible with the Arduino 5V. This code is for enabling control of the player using a remote control. Serial.println(" [e] seleciona equalizacao"); Serial.print("Volume atual:"); Code for playing audio files on the memory card. So each time, the scheme will be printing the Options Menu you have, with commands, directions. equalizacao = 0; mySoftwareSerial.begin(9600); myDFPlayer.EQ(0); //Equalizacao normal Add the following "DFRobotDFPlayerMini" library for communication with the mp3 module. Start by creating one object, the serial software, and another, which is myDFPlayer. For the signals to the micro is not necessary, the 3.3 V are interpreted as high level without problem. 8KHz,11.025KHz, 12KHz,1 6KHz, 22.05KHz, 24KHz, 32KHz, 44.1KHz, 48KHz. The DFPlayer mini module has an in-build amplifier which can drive up to 3 watt loudspeakers in stereo or mono. Serial.println("DFRobot DFPlayer Mini"); { 4 BY Eu. How to use the 74HC595 Shift Register with Arduino. maxSongs = myDFPlayer.readFileCounts(DFPLAYER_DEVICE_SD); We can build a simple mp3 player using this module. menu_opcoes(); { For example we can an IR remote control whose set up will be done as shown below. DFRobotDFPlayerMini myDFPlayer; The popular mp3 music file is converted to wav file, stored in SD card module, then it is read by arduino and output to speaker, #include // need to include the SD library, #define SD_ChipSelectPin 10 //pin10 for Arduino Pro Mini, #include // Lib to play wav file, TMRpcm tmrpcm; // create an object for use in this sketch, tmrpcm.speakerPin = 9; //pin 9 for Aduino Pro Mini. if (equalizacao == 6) Serial.print("Reproduzindo musica: "); Follow my channel on Youtube and my Blog. int maxSongs = 0; In this step, we put options of prints to give you indications that it is mounting the circuit, with evaluations of false conditions, for example. My only problem was low memory using the UNO board sot I switched to Mega 2560. How to use the 2.4" TFT LCD Touch screen shield for Arduino. For this assembly, we are specifically using the Arduino Uno, but you can also connect to ESP8266 or ESP32. Serial.println(maxSongs); } { We'll start by defining the libraries and constants we'll use with our code. }, void loop(){ Reply else Both the SD as the MP3 module are connected to the Arduino using the SPI bus. Easy project can be completed in 10 minutes! renatoalves1900@hotmail.complease contact, I have a question...If playing an MP3 song...then I turn it OFF...when tunr it ON again.it will start playing from beginning or it will continue from last played song ?Thank you, Hi!,It looks awesome!What kind of encoder did you use?Kind RegardsJory. 2 { You can also use a SparkFun MP3 shield, but significantly more expensive (this shield already includes an SD slot). Serial.println("Modulo DFPlayer Mini inicializado! 328P chip used in stand alone mode (with the appropriate matching pin) but the circuit does not work. menu_opcoes(); You control this entire assembly through the serial monitor. making project playing music with LEDs. L293D Motor Driver for Controlling DC and Stepper Motors. 1 //Inicializa a serial do Arduino //Mostra o menu de comandos About: Do you like technology? I need to have button 1 play file 1 and button 2 play file 2. MP3 Player With Arduino: In this assembly, we used an mp3 player with Arduino Uno, a mini PAM8403 sound amplifier with volume adjustment, an mp3 module DFPlayer Mini, and a pair of 3-Watt speakers.This scheme serves not only for the music player, but also to allow voice fun… If anyone want's a faster and simpler library to use with this module, I suggest using this one: https://github.com/PowerBroker2/DFPlayerMini_Fast. { Then decide which buttons you will use for controlling the mp3 player. and it works. Share it with us! //Definicoes iniciais There are no updates to this project? 6, Make reference to another post about ir remote control to learn how to decode the ir remote. Please where do we download the “DFPlayer_Mini_Mp3.h” file or library? //variável responsável por armazenar o estado da equalização Hi, the only one I could get to work properly was the “controlling the MP3 player with buttons”. This mp3 player module can be connected to the Arduino as illustrated below. { It has 24-bit digital to analog converter (DAC), There are many other specifications for this module which you can look up in the DFPlayer mini module. NOTE: i).Don’t forget connecting a 1k resistor between Arduino Tx and the MP3 module RX otherwise you will have poor sound output. Serial.print("Numero de arquivos no cartao SD: "); Hardware need. The popular mp3 music file is converted to wav file, stored in SD card module, then it is read by arduino and output to speaker.
