Thank you very much. Please note that you should use a 3W speaker or one with lower power rating. If you don't have a 3W speaker, you can use a 5W speaker with a series resistor (20 ohms or more), and it can work, as I have done.

[@UliSpalthoff]

Isn't the load to the amplifier defined by the Ohms rating, not by the power rating? afaik, The speaker power just tells which power the speaker can handle without distorting sound too much.

Great Video. As you, I was having problems getting my player to play all the files after formatting my disk using WIN10. I found that if you don't use the quick format your MP3 player will play all of you files. I have about 700 songs on a disk and by using the randomALL command it plays all of the songs loaded. Also, I don't any number or folders assigned to the songs. Hope this helps.

Just worked through an issue I had with this board, one that others may also have, so I thought I'd share. Everything was connected correctly, the code was implemented and uploaded. But the only serial output was "MP3 Player Online." After messing around with the code and it still not working, I switched out my Arduino Nano for an Uno, and that instantly fixed the problem. I think my Nano is an older model, without an ESP32. So check for microcontroller compatbility! Otherwise, a great tutorial and header file. Thanks!

Nice video, Thanks for sharing. I wish to add the MP3 player function to a selfbuilt Nixie clock and turn it into a "talking clock". For this purpose, I need to concatnate different MP3 files depending upon the time the clock is going to announce. My question: Does the MP3 Player library allow concatanation of files? Thanks for your comment/advice in advance.

[@thelastoutpostworkshop]

Nice project! You don't need to concatenate the MP3 files (and the MP3 player don't have this functionnality), you can select which one to play by using code depending on the hour. Here is a very simple example : #define trackFor12 20 #define trackfor11 25 switch (hour) { case 12: mp3.playTrackNumber(trackFor12, 25, true); break; case 11: mp3.playTrackNumber(trackfor11, 25, true); break; break; // and son on }

Did you experience different speed of playback using more than one of modules? I hooked up three of them, Start them simultaneously, same as cards, same file and they start synchronous, but drift about 1 sec within 6 minutes playback. So speed of playback is not identical on these modules, good only for doorbells, but not for serious applications, or?

Thanks for the video! Is it also possible to use a button to cycle through the sounds while they still play in a loop? So that when the sound is done playing it jumps to the next sound, but when it is playing and you want to skip this sound you can press the button to go to the next? I tried a few things but can't get it to work.

[@thelastoutpostworkshop]

yes you can do that, just specify false for the last parameter when starting a sound : mp3.playTrackNumber(sound, currentVolume, false); So the sound will start playing and your code will not be blocked, you can then do anything you want while the sound is still playing, including starting a new sound!

[@Ninanas98]

@@thelastoutpostworkshop Thank you for the reply! I tried it like this if (digitalRead(buttonNext) == ACTIVATED){ i ++; } mp3.playTrackNumber(i, 4, false); but the sound keeps starting from the beginning until you start the last sound in the folder, that one is played fully. Would it also be possible to combine it with a for loop or something so when you don't press the button the next sound will automatically play after the current sound is finished?

[@thelastoutpostworkshop]

if you want to play a sound automatically after one is finished, you can do it this way : mp3.playTrackNumber(sound1,15,false); while(!mp3.playCompleted() && !buttonPressed) { } //play the other file

[@marckerger]

how can I use your script on a board with hardware serial1 ? mine does not support softwareserial

[@thelastoutpostworkshop]

Here’s how you can modify the MP3Player class to use a hardware serial port instead of a software serial one. The changes mainly involve removing the SoftwareSerial object and assuming you will use a predefined hardware serial port for communication with the DFPlayer Mini module: #include "Arduino.h" #include "DFRobotDFPlayerMini.h" #define MP3_ERROR_ONLY 1 #define MP3_ALL_MESSAGE 2 class MP3Player { private: HardwareSerial *mySerial; // Pointer to HardwareSerial instead of SoftwareSerial void statusOnSerial(uint8_t type, int value); void waitPlayIsTerminated(void); public: DFRobotDFPlayerMini player; // Constructor now takes a reference to a HardwareSerial object MP3Player(HardwareSerial &serialPort); ~MP3Player(); void playTrackNumber(int trackNumber, int volume, boolean waitPlayTerminated = true); boolean playCompleted(void); void initialize(void); int serialPrintStatus(int errorOnly); }; // Constructor implementation changed to initialize the HardwareSerial reference MP3Player::MP3Player(HardwareSerial &serialPort) : mySerial(&serialPort) { } MP3Player::~MP3Player() { } void MP3Player::initialize(void) { mySerial->begin(9600); Serial.println(F("Initializing MP3Player ...")); if (!player.begin(*mySerial,true,false)) // Use the HardwareSerial reference { 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) ; } player.volume(10); Serial.println(F("MP3Player online.")); } // The rest of the implementation remains the same...

Greetings I am using the Gravity Digital Speaker Module for the MP3-TF-16P project, but my speaker has 3 pins. For my my connection I tried connecting the VCC and GND of speaker to the Arduino Mega, then the signal Pin to SPK1 of the MP3, I eventually connected signal pin to all other pins of the MP3 player but there is still no audio sound output, the speaker produces a scratchy sound The MP3 blue light is not turning on but on the serial monitor it says “MP3Player online” May you please assist me?

[@thelastoutpostworkshop]

I am not sure if it can work since the gravity module has a digital interface when SPK connections on the MP3-TF-16P are analog, but it also have DAC_R and DAC_L pins, have you tried these ?

[@michaelcoles4181]

Thanks for this video, I'm new to this and found it very informative. I've got the player to work as instructed but I'd like to play two tracks basically an engine on/off effect. Track 1 (engine startup) would play continually as long as a momentary switch is pressed then track 2 (engine cool down)would play automatically when the the switch is released. Could this be done and where would I wire the switch?

[@thelastoutpostworkshop]

Yes it can be done, you can wire the switch on pin 7, and use this to initialize it in the setup() function: void setup() { pinMode(7, INPUT_PULLUP); // Rest pf your code here } then in the loop function you read the push button: void loop() { if (readPushButton()) { // Play your first MP3 file while(!readPushButton()) { // Here we are just waiting for the push button to release } // Plya your second MP3 file } Here is the function to read the push button: boolean readPushButton(void) { int value = digitalRead(PushButtonPin); delay(5); return value == 0; }

How can we use DFPlayer mini with Arduino Nano 33 IoT ?

[@thelastoutpostworkshop]

Yes, the DFPlayer Mini can be used with the Arduino Nano 33 IoT. However, there are a few considerations you should take into account due to the differences in operating voltages and the additional features of the Arduino Nano 33 IoT. Voltage Compatibility: The Arduino Nano 33 IoT operates at 3.3V, whereas the DFPlayer Mini typically works with 5V signals. To safely connect the TX and RX pins of the DFPlayer Mini to the Arduino Nano 33 IoT, you might need to use a level shifter or a voltage divider to step down the 5V TX output of the DFPlayer to 3.3V acceptable by the Arduino's RX pin. Serial Communication: The Arduino Nano 33 IoT has one primary serial port used for programming and debugging over USB. To communicate with the DFPlayer Mini, you can use software serial on other digital pins.

Good evening, I'm trying to start the player but it says MP3 online, but nothing works, what could be the error? Can you help me please?

[@thelastoutpostworkshop]

Reeheck your wiring. Make sure the TX and RX pin are not reversed. Do you have any error message on the serial monitor when playing a sound file ?

[@user-fo9qs2vg9s]

@@thelastoutpostworkshop no, nothing appears. Everything is connected correctly, there are no errors. I would attach a photo here, but this is impossible. Can we write to each other somewhere on social networks? I will be very grateful to you!!!🙏🙏🙏

Hi can you help me..i want to use your "mp3tf16p.h" with hardware serial..thank you very much.

[@thelastoutpostworkshop]

Here is the code for using Harware Serial : #include "DFRobotDFPlayerMini.h", be aware that it is used for Serial for communication with your computer over the USB port : #define MP3_ERROR_ONLY 1 #define MP3_ALL_MESSAGE 2 class MP3Player { private: void statusOnSerial(uint8_t type, int value); void waitPlayIsTerminated(void); public: DFRobotDFPlayerMini player; MP3Player(); // No pins in the constructor now ~MP3Player(); void playTrackNumber(int trackNumber, int volume, boolean waitPlayTerminated = true); boolean playCompleted(void); void initialize(void); int serialPrintStatus(int errorOnly); }; MP3Player::MP3Player() // Constructor doesn't need parameters now { // Empty constructor } // ... [Other methods remain unchanged] void MP3Player::initialize(void) { Serial.begin(9600); // Start the hardware serial port Serial.println(F("Initializing MP3Player ...")); if (!player.begin(Serial, true, false)) // Pass the hardware Serial { // ... [Unchanged error handling code] } player.volume(10); Serial.println(F("MP3Player online.")); }

Did you install the library DFRobotDFPlayerMini from the Arduino IDE library manager ?

how many sounds tracks can be played at the same time ?

[@thelastoutpostworkshop]

only one

[@he214abc]

@@thelastoutpostworkshop i played rc tank, many sound tracks needed to be played at the same time, like 5 channels, then what i should use instead ?

[@rosmanminiatures]

I have tried this and, for sure not 5 chanels but a couple, and you have to conect as many dfplayer as channels you want, with only one speaker needed. For example in your case, i supose the noise of the engine sound will be one channel and at the same time when the canon shots you want to hear an explosion, then you play this on the second one. The dfplayer has to be connected to another pin set for RX TX comunication. And i reccomend to think about if you really need those five channels or if you can simplify them in less because all that will be so pin consuming

SD card format program does not work, loads then does nothing??

I reinstalled it and it worked just fine

[@retrobombstudios1258]

Could a pico run this?

[@thelastoutpostworkshop]

I did not try it, my only concern is the DFRobotMiniplayer library compatibility with the Pico, but since the MP3 player use standard serial communications, it should work. Give it a try!

does it not work with 64 GB Sd card ????

No

But I think you can format it as 32GB

Initializing MP3Player ... MP3Player online. -1 How I solve it, I have a 32GB micro SD card and good connections to the pins of the MP3-TF-16P to the Arduino, and only one song.

[@thelastoutpostworkshop]

I f you have 1 song, make sure you pass the track number 1 in this function : mp3.playTrackNumber(1, 25,false); If this is the case, recheck you wiring, it easy to mix-up RX and TX pin
