Il mini lettore MP3 DFPlayer per Arduino è un modulo MP3 piccolo e conveniente con un'uscita collegabile direttamente all'altoparlante.
Die Drehregler sind KY-040-Drehgeber, sodass sie sich in beide Richtungen drehen lassen, ohne anzuhalten.
Here I am using Arduino Nano instead of Uno, The module can be used as a stand alone module with attached battery, speaker and push buttons or used in combination with an Arduino UNOor any other with RX/TX capabilities.
but you will get less noise if you connect your Arduino to the right side of the DFPlayer Mini board.
where I connected the Arduino serial output pin directly to the DFPlayer Mini board's RX pin. DFPlayer Mini datasheet: Here is an example of the phone's speaker: Stereo Speakers.
Open a terminal window and enter:
DFPlayer Mini has a 3W amplifier on the board. could not deliver enough current for it to work reliably. Preis: $7 $8 / Inklusive Steuer Bestand: Auf Lager (994 Stück), versandfertig. I just have some concerns.1.) Rx - D11 Tx - D10 VCC - 5v Gnd - Gnd Go over the connections once again to ensure everything is as it should be. Through simple serial commands to specify music playing, as well as how to play music and other functions, without the cumbersome … You can organize your files into sub-folders – up to 100. The following components are required to build this project; 1. It says that the DFplayer can play on folders as well. This shouldn't be done since input pins of the module are not 5V tolerant. This is a step-by-step guide in video form. The player doesn’t know what you call “next”. Then connect a wire from between the resistors to the module's RX pin. Table of content: QTY DISCOUNT; 2-4 $8 .80; 5-9 $8.60; 10+ $8.10 * Model: [[item.name]] Quantity:-+ BUY IT NOW ADD TO CART. The sound would be triggered every revolution and needs to increase with rotational speed. Mengenrabatt auswählen: 1x MP3 Player. Each folder can contain 255 MP3s. I have mostly used cheap 8Ω speakers off of eBay,
but connecting ground to ground without connecting to the common ground won’t work.
Mono Speaker.
DFPlayer Mini's digital input pins are not 5V tolerant. but it was probably higher than 8Ω. Click on the green "Clone or download" button and then "Download ZIP."
You should create a voltage divider by connecting a 680Ω and a 1kΩ in series from Arduino D2 to GND. But I have one more issue. I have mostly used cheap 8Ω speakers off of eBay, If you want a device that is able to record and play a message then please visit: Hello, this is really helpful for beginners like me! DFPlayer - A Mini MP3 Player. It need not be connected to the Arduino. You can connect one mono speaker to the module or two speakers in stereo mode.
You can connect one mono speaker to the module or two speakers in stereo mode.
This means that you can access a file with values from 1 to 255. In this video, I am using a voltage divider for the RX pin. between the IO pins. It is possible to power DFPlayer Mini with 3.3V,
but in my experience, the 3.3V voltage regulator on the Arduino board
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?
Sparen Sie $1. and I want to ad 3 DC motors on that program and LED ligths…2. This article is very important for those who want to add some sound or voice effects to their projects. The situation is this: In my SD card, I would like to upload atmost 5 mp3 files. Do you have any instructions when you add an amplifier am8403 on this set up?3.) It's the same deal with folders. DFPlayer Mini 2. The first folder you created will be 1; the second one will be 2, etc.
If that ground is not connected to the Arduino’s Ground the module will NOT come on. Here is an example of the 8Ω speaker in action: Arduino Buch. 5x MP3 Player. Then you can send commands to play MP3 files on the SD card. As a next step, you can follow the examples that come with the "DFRobotDFPlayerMini" library. between the IO pins.
