Many people had trouble with that. I am using the 1N diode to reduce the voltage by approximately 1V. In three different projects, this always worked for me. Hi Markus, would it be possible to connect dac l, dac r and gnd to the aux input of a typical domestic hifi amplifier, or would the levels be all over the place? Thank you, Andrew. Andrew, yes, this is exactly like the PAM amp is connected - that should also work for HiFi amps. Of course, to be careful, I would initially set the DFPlayer volume, and the amp volume to a very low level.
Two points: with the DFPlayer I recently bought, there is no data coming back after the first dfpExecute code. So mySerial. Just comment the while and it works. Also, after the dfpExecute 0x0F,0x01,ifile ; in the loop, you need to add a short delay eg delay Because the busy line is not set immediatly after the call. So if you test it just immediatlty after calling dfpExecute 0x0F,0x01,ifile ; you get a wrong result, telling no mp3 is playing and so you just start to play the next file. Hope this help!
Markus- Thanks for the tips related to the 3 modes of operation. But then I found that this happened only due to interference of the serial connections, because the Arduino was still connected to my PC. Once I disconnected it, it worked.
And thank you for pointing out the feature of the delayed response of the busy signal. In my applications this never happened, probably because I am only checking the busy signal after longer time intervals. After a couple weeks of research, your work was the most concise and functional application of the code.News 9 at 10
Thank you for posting your knowledge! Thank you, Creston. I'm glad this was helpful for you. In the meantime I have used this in about ten different projects.In this post we are going to construct an Mp3 player using arduino and DFPlayer. The proposed article has two Mp3 player designs, one with push button control and another one with IR remote control.
We will also take a look at DFPlayer Mp3 player module and its specifications. We all love music, we would like to hear it while at gym, reading, moments before sleeping or while soothing our self after a hard day work. Constructing a music player at home few decades back was a near impossible for an electronics enthusiast because of constructional complexity due to mechanical components. In those days only limited number of songs could be accommodated in a cassette. Replicating a song to another cassette was a nightmare too.
But now, thanks to advancement in electronics an Mp3 player can be made from scratch with your pocket money. The heart of the project is DFPlayer which is a small Mp3 player module which can accommodate micro SD card and can be controlled using a microcontroller.
It has in-build amplifier which can drive 3 watt loudspeakers in stereo or mono. It has bit digital to analog converter DAC which is pretty good for such low cost and compact module. It supports sampling rate of 8KHz, It can support up to 32GB micro SD card. It supports up to folders, each folder can be assigned up to songs. It has 6 different levels of equalizer; and 30 levels of volume adjust control. It can operate from 3.
By now you would have familiar with DFPlayer and its specification. You can purchase this module from e-commerce sites or from local electronics market. The above circuit is very simple; the arduino sends commands to the DFPlayer module to control the songs. The user can input their choice via push buttons. If you find any distortion in the sound at higher volume levels, power the DFPlayer module externally at 5V DC with common ground connection between arduino and DFPlayer.
The above design is simple as the push button based; the only difference is removal of push buttons and inclusion of TSOP IR receiver.Please enter your details below and we will send you an email when this item is back in stock.

The decision is yours, and whether or not you decide to buy something is completely up to you. You can connect a single mono speaker to the DFPlayer Mini module or two speakers in stereo. Click on the buttons to switch between the schematics.
It is 5V tolerant. It is possible to power DFPlayer Mini with 3. DFPlayer Mini has two Ground pins. It will work with either of the Ground pins, but you will get less noise if you connect your Arduino to the right side of the DFPlayer Mini board. The left GND is meant for stereo speakers. Make a voltage divider between Arduino D2 software serial data transmit pin and module's RX data receive pin.
DFPlayer Mini's digital input pins are not 5V tolerant. Then connect a wire from between the resistors to the module's RX pin. Connect Arduino D3 software serial data receive pin to the module's TX data transmit pin. For stereo speakers, connect one wire of both of the speakers to the left GND between the speaker wires.
A step-by-step guide in video form. Here I am using Arduino Nano instead of Uno, but the pins are the same. This shouldn't be done since input pins of the module are not 5V tolerant.
In this video, I am using a voltage divider for the RX pin. DFPlayer Mini has a 3W amplifier on the board. The lower the impedance, the louder the maximum volume can be. It was pretty quiet but about right for a phone's handset. Extract the downloaded ZIP file and move it into your Arduino "libraries" folder.
This is a simple example that starts playing the first MP3 file on the SD card after Arduino start up:. It has commands to start and stop a song, play the next song in the sequence, play a song in a loop, etc.
Instead, you must use a file number. It supports up to files per folder. This means that you can access a file with values from 1 to You can organize your files into sub-folders — up to Each folder can contain MP3s. The number of a file is determined by the order that it is copied to the SD card. Renaming files that are already copied to the SD card will not change the file number! When I am preparing an SD card for the module, I always add prefixes to the file names before copying them over.
Then clear the SD card and copy all the files onto it. It's the same deal with folders. Names do not matter. The first folder you created will be 1; the second one will be 2, etc. This command will remove all the hidden ". Play MP3 Files with Arduino.Hi guys, welcome to this tutorial.
Some of the features of the DF player mini include:. The goal of this tutorial is to demonstrate the use of this module with Arduino, using the push buttons to instruct the Arduino to send serial commands to the module and control mp3. We will use three buttons to achieve this.
The connection is described below for clarity. Go over the connections once again to ensure everything is as it should be. Our switches are intentionally connected without pull up or down resistors because we will enable the Arduino internal pull up resistors. To send commands from the Arduino to the DFplayer mini, based on the button pressed, we will use the Arduino software serial library. While we could have used the hardware serial to send commands from the Arduino to the DFplayermini, the Arduino hardware serial pins 0 and 1 are the same pins used by the Arduino to communicate with the computer and may prevent code to uploaded smoothly if connected to any other device.
So to communicate in a stress-free manner we will use the software serial library with pins 10 and The code for this tutorial is simple, while the DFPlayer mini has a library which contains different functions for controlling the mp3 player, we will write our own functions for the fun of it and to help show how the module really works. The first thing we do in the code, as usual, is to include the libraries that we will use which in this case is the software serial library, creating an object of the library while declaring the Rx and Tx pins 10 and 11 respectively.
With this done we start the software serial communication with a baud rate. Next, we play the first song on the storage device using the playfirst function and set the isPlaying boolean variable to true to indicate that one of the files is currently playing.
The complete code for the project is available below and can be downloaded from the download section of this tutorial. Load an SD card with songs and insert into the DFplayer mini, then upload the code to your Arduino and connect the wires from speaker to the speaker pins of the DFPlayer mini.
You should hear songs start streaming out from the connected speaker. Your final setup should look like the image below. Some of the applications of this tutorials are listed below and I hope it gives you the inspiration to build something really cool. If you get stuck anywhere feel free to send your questions via the comment section. The video tutorial for this tutorial can be watched on youtube here. The ground from Arduino to player should not go there.
It should connect to the other ground on the player to prevent unwanted noise. You mean the other ground should also be connected to the common ground? But if you mean connect the other second ground on the module to the common ground for the Arduino then yes, that can be done if you discover you have noise. It need not be connected to the Arduino. One GND to the speakers, the other to Arduino. That is the only way to stop the unwanted noise.Pages:  2.
Hello, I have an arduino nano and i am trying to wire up and code the dfplayer to play sounds. I can not get any sound to play at all. If it is not possible to wire them using the tx an rx could it be wired without using the pwm pins? Re: dfplayer wiring to arduino nano using rx and tx and code issue. Give us more details - code you have using code tags - drawing of ALL the connexions including USB if connected to a computer - links to the board you have.
Quote from: casualgamer24 on Nov 13,pm. So ill have to use non pwm pins or the tx and rx pins. Quote from: casualgamer24 on Nov 14,am.
Mp3 Player Using DF Player – Full Design Details
You don't need any PWM pins. You need a serial interface. If you're using the one hardware serial to upload and talk to serial monitor then you need software serial to talk to your module.
Any pins can be used for software serial. I've used a bunch of words that if you don't know what I'm talking about Professor Google can probably help a lot. Keep Arduino stuff out on the boards where it belongs. Trying to get back into electronics after 15 years absence. I'm not sure if SoftwareSerial works on analog pins I think it does but you are aware that analog ins can be used as digital IO? Maybe a solution.
If you understand an example, use it. If you don't understand an example, don't use it. Electronics engineer by trade, software engineer by profession. SoftwareSerial will work on any digital pins, even the ones that double as analog inputs. Remember, they're digital pins first and the analog thing is something extra they can do. Post your schematic.
Arduino Project: MP3 player using Arduino and DFPlayer mini MP3 player module
What you actually have, not what you tried to copy from. Post your code. There is very very little that anyone can do to help you without being able to see what you did. Does that make sense to you? I have no experience with the dfplayer but it does not help to include SoftwareSerial and not use it Maybe start with some reading; SoftwareSerial Library.
Code: [Select]. His code might give an error, but it wouldn't get that particular error.The music files to be played using the DFplayer mini are pre-stored on an SD card which is inserted into the DF player mini.A new approach to model regime switching
For this tutorial, we will be using the Arduino Uno, but you can use any other Arduino or microcontroller to build this project. The following parts are needed to build this project and each part can be bought by clicking on the link in front of it. Full disclosure: All of the links above are affiliate links. I get a small percentage of each sale they generate. Thank you for your support! As shown above, the connection between the Arduino and the DFplayer mini is pretty simple.DFPlayer Mini - MP3 модуль с портом UART
The pin connections are described below to make it easier to follow. A speaker is connected to the speaker output pin 6 and 8 of the DF player mini to air the sound being played. Go over the schematics once again to ensure everything is as it should be before proceeding to the code.Bisogni linguistici specifici e apprendimento della grammatica
Although the DFplayer mini has its own library that enables us to write the code easily, it is not used for this tutorial, Instead, we created functions which can be called to perform the tasks involved with this project. Additional functions can be found in the description of the video on youtube.
The first thing we do in the code is, as usual, include the libraries needed for the project; in this case, the software serial library.
Then we declare the pins on the Arduino to which our pushbuttons and Dfplayer mini are connected. Next, we move to the void setup function. With the setup function done, we write the loop function. This, as usual, contains the set of code that will run forever.
The void loop function works by reading the state of the pushbuttons after which it calls the function corresponding to the pushbutton state to either play, pause, play next mp3 or play the previous one. See you next time. Never miss a video: Subscribe to educ8s. Do you have any plans to up date this video? I have make this but would like some help to make this into a potable mp3 player with a Stereo Audio Jack Socket, a battery and a USB connection ideally I would like something that uses all the DFPlayers functions.
I have been looking for a simple PCB etching project and think this would be perfect starter project. I am a student, and please help me. When the loudspeaker is connected is not clear to me the steps. Hi, I have a few sounds file on my SD card. How I can play specific file? For example I want play I did a soundboard using this module and code! Very good, i also recommend going to the link with the modules commands.
The rest are just sound mp3 files. Keep in mind the order of which you added the files to your SD card is what determines their play order.
How would I go about changing the code? I have three files on the sd card namedand ? Can you please tell me about this project the possible ways to adjust the volume? Can I use buttons or a potentiometer? Yes, you can do that.
