One GND to the speakers, the other to Arduino.
I want to add a display to the project …I dont think so. The other GND which is not used in this sketch should go to Arduino’s GND. Cheap Arduino Uno 3. The following components are required to build this project; 1. 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. I’m using a silly Text send from app inventor to arduino in order to select the mp3 file I want to play.But I really need to figure out how I can send the track list on the SSD card.Does anyone know if such thing is possible? The bottom one is the electricity input. If I do so then the next songs plays for few seconds and then the clicking noise starts. can I add something to the code so the players plays Random and only stops when I push ‘next’ or ‘pauze’ or ‘prev’ ?Is it possible to capture the MP3ID or filename ? Required fields are marked with *.The DFPlayer mini module can be used where you want to include sound or music in your projects and in this tutorial i will show you how to interface this module with Arduino.The DFPlayer mini is a small low cost mp3 module that can directly connected to a speaker. The top GND is only for the speaker. Sending execute_CMD(0x08,0,3) doesnt seem to make any difference?No no no… GND is GND and they should all be connected. Just like most talking toys do.
I’m sorry if it’s a silly or obvious question. I would like to build an mp3 player with arduino uno, dfplayer, amplifier pam8403 soon. The two are not one and the same as the diagram would make you believe. So I guess I’m making progress rather fast.The only thing I really need to do now is find a way to retreive data from DFPlayer module to my App. If that ground is not connected to the Arduino’s Ground the module will NOT come on. We can build a simple mp3 player using this module. The player has two GND (ground) connections. I am not sure what am doing wrong.I did exactly as has been provided in the instructions. Can this gizmo work that way without the Arduino for a sound .You can MUCH more easily control and query your DFPlayerMini by using a library like DFPlayerMini_Fast.h: wonderfull ! 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). Buttons 5.
Today, we will build an mp3 player using an Arduino and the DFPlayer mini MP3 module.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. The player doesn’t know what you call “next”. It should be noted that the 1k resistor added in between the Rx pin of the module and the Arduino was added to reduce noise but it’s not necessary if your module setup is not accompanied with noise on the Rx line.
The lower GND is for the power source. like if I just played track 5, the next trigger button would play track 1. or if I am on track 1, if I hit the previous, it would play track 5. and another issue is that I want the music to go louder… can I add an amplifier to this?3. and I want to ad 3 DC motors on that program and LED ligths…2. I am not a tech guy, but I enjoy the knowledge that you share with us…CAN YOU COMBINE BOTH IR REMOTE MP3 PLAYER AND THIS AND ADD LCD DISPLAY TO SEE MP3 NAMEYour email address will not be published. There are many other specifications for this module which you can look up in the DFPlayer mini module This mp3 player module can be connected to the Arduino as illustrated below. After learning the basics of how the DFPlayer mini module works and how to use it with Arduino we can be able to do a more intersting project. From the schematic, we remove the push buttons and instead include a TSOP1838 IR receiver whose signal pin is attached to pin 7 of the Arduino.If you do not know how the IR receiver and remote control work you can make reference to my other tutorial : Small Breadboard 4. That is the only way to stop the unwanted noise.The volume is predefined in the code in the range 0-30. Wires 8.
