Learn How To Interface DFPlayer Mini MP3 Module With Arduino

It won't recognized by the Arduino board, and it does literally nothing. I wired the module according to the connection diagram see Reference aboveloaded up the sample code, but this gives me just "Unable to begin Also, i connected a speaker 4 Ohms, 3W to the player.

The Arduino itself is currently powered by USB. Does anyone have an idea how to get the serial communication or the module itself working?

Source Code only, which i used as base. Have you tested the player using one of the provided example sketches, with no other components connected to the Arduino? Have you tried using one of the hardware serial ports on the Mega, instead of software serial? Did you get the replacement player modules from the same supplier as the original? Yes, i already tried some different example sketches also see the last link in my first post. And, as already written, i tried SoftwareSerial and Serial1, Serial2, No, three different suppliers the last one was Amazon i think.

Have you tried using the player stand-alone? Okay, i created a testing circuit see attachment now, plugged everything in, inserted my SD card and: No sound.

How long does the led stay lit? Does the led stay lit for the length of that track? Yesterday i solved the problem. I bought another DFPlayer, swapped the old one out and: Problem solved. The problem was the amplifier chip, and, seems i got very unlucky, all three chips of the other DF's don't work as they should.

The problem with the UART communication was a damaged resistor I measured it and there was no connection between the pin's. So 3 different players from 3 different suppliers all had the same fault? However, the other ones are from the same manufacturer i measured the amplifier chipsbut from a different vendor. Quote from: essigwurst on Aug 14,am.Would you like to create a sound unit you can use in different ways, uploading the sounds you want for your scratch built toys, in a matter of seconds?

Jumper Wires Male to Female 20 cm you'll cut them to the right size, according to space you have in your box. Did you use this instructable in your classroom?

Add a Teacher Note to share how you incorporated it into your lesson. Add 2 jumper wires Femaleto the same push-button, to have another open momentary switch, that eventually is going to be triggered by an Arduino board. Please use the soldering on iron carefully and insulate every connection using the heat shrink tubing. In one of my previous projects, I used a slightly modified box of the Ikea Vackis Alarm Clock, to create a portable mp3 player.

Using UHU Por, I've glued the push-buttons and later I've poked 2 holes on the left side Battery and USB and 1 on the right side for the cables of an "eventual" digital push-button activated by an Arduino board.

Now you can upload your favorite sounds, creating on the sd card you have previously slotted inside the DFplayer Unitthe directory mp3 in the root i. There is only one downside in using the DFPlayer. You have to put a sequential number in front of the title of your sound i.

Or you can simply press the push-button on the unit, you are going to attach to your remote control By RC Lover san Follow. More by the author:.

Welcome to my "ible" Here comes the tutorial that explains how to do that, using a DFplayer unit. Add Teacher Note.

For my toys instead, I've built a smaller box, using a 5mm piece of A3 foam board. I basically cut 2 pieces 6x5cm front and back, 2 pieces 6x3cm and 2 pieces 5x3cm. But at this cheap price, I believe you can deal with it!

【MP3】DIY Electronic Music Box with DFPlayer Mini【Orgel】

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.Is my speaker just too small? Is this the right impedance?

This is my first electronic hobby project, so I am not very fluent in speaker lingo. Any suggestions on what I should try would be very helpful. Like to post a picture of your structure? I finally had time this week to sit down and troubleshoot a bit. Only after trying several different speakers that I had around, did I realize that it was actually the waffle board that Ihad my initial setup on that was not providing a very good connection.

I went ahead and soldered everything together with the original speakers, and now it works great. I am using a 4. DFplayer mini sound too quiet, low volume Troubleshooting. Cthomas October 14,am 1.

Cthomas October 30,pm 6. ScruffR October 30,pm 7. If you want to add some glamour to your setup, you could have a look at this.This is an mp3 audio player built from a esp wifi module and a dfPlayer mp3 module.

It plays files from a SD card. I housed it in an old computer speaker and made it battery operated, but it could be built into any speaker enclosure. Stereo to headphones. Did you use this instructable in your classroom?

Add a Teacher Note to share how you incorporated it into your lesson. The dfPlayer module can be tricky to mount as it needs to have external access to a slot for getting at the SD card. The details of the mechanical construction will vary with the type of enclosure to be used. The example here used computer speaker unit. This had plenty of room inside for the modules and electronics.

The picture shows the completed view for this example. The USB, power switch, and push buttons are on the right hand side. The LIPO is mounted on the back. The battery was mounted on the back. The ESP software is written in the Arduino environment. The other libraries required and listed there are standard modules. The ino sketch does not need much changed although you will want to change the WifiManager and firmware update passwords.

Compile in a Arduino ESP environment and do the first flash over the standard serial connection. Further updates can be done by exporting a binary file in the Arduino IDE and doing an OTA over the air update direct to the unit without any wires. On first use the software will not have the local wifi credentials but instead will create an Access point itself called dfPlayerSet up.

Connect to this e. This will bring up an interface to allow selection of the real network and enter its password. From then on this will be used automatically.

Now because my project have to be as small as possible, I used a smartphones loudspeaker the Iphone 5c ones but I couldn't find out its rated wattage!

So I took the risk and wired the speaker to SPK1 and SPK2 pins on the the DfPlayer mini, set the volume to max aaand the speaker is producing pretty decent loud and fair quality sound! The question is does anybody know the max wattage for such speakers or any modern smartphone speaker? According Ohms's law, the wattage should be 0.

Googling something like smartphone speakers wattage didn't help. Amateur radio sinceapproximately. Live in Central Oregon desert. Re: Smartphone loudspeakers with Arduino and DfPlayer mini. You are mixing apples and oranges. Speakers are rated with impedance of 8 ohms because the audio is AC at various frequencies.

Measuring and computing DC values do not apply. An 8 ohm DC resistance means the impedance is probably quite high, so your 3 watts, also an AC value, won't hurt it. How loud can you make the phone ring sound on your smart phone? That is probably close to the speaker limit. Quote from: Karro on Jan 10,am. The power rating of a speaker will correlate with the size of the motor the bit with the magnet and voice-coilso you if you find a similarly sized unit it will have a similar power rating.

Power ratings are all about getting rid of the heat generated in the voice-coil. Note that the efficiency of a speaker how much sound for a given electrical input is an entirely separate issue, and efficiencies can vary a lot with speakers, but I strongly suspect iPhone speakers are high-efficiency due to the demands of a battery-powered device.
