Lab: Tone Output Using An Arduino
Hi guys, welcome to this tutorial. The DFplayer mini is a small, low-cost mp3 module with a simplified audio output that can be connected directly to a speaker or an earphone jack. 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.

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. The volume is predefined in the code in the range DFPlayer Mini can only play mp3 files. The situation is this: In my SD card, I would like to upload atmost 5 mp3 files. So, if I trigger the next button, it would play track 1 only, for example, then hitting it again, would play track 2 and so on. Then this would go on a loop.
Just like most talking toys do. It says that the DFplayer can play on folders as well. Is it possible to set up push buttons that would select the folders it would play? Like button A will play the mp3 files on folder 1 while button B on folder 2 and so on?
I have set this up exactly as mentioned and it works great as long as I do not push the previous or next button. If I do so then the next songs plays for few seconds and then the clicking noise starts. I am not sure what am doing wrong. I did exactly as has been provided in the instructions.
But once I press the previous or next button the next song plays for few seconds and then the clicking noise starts. The diagram presented on this page is wrong. The player has two GND ground connections. The top one on the diagram is for the speaker.
The bottom one is the electricity input. The two are not one and the same as the diagram would make you believe. Thanks a lot Emilio for your help!! Your suggestion helped in stopping the noise.
But I have one more issue. It does not automatically play the next song in the list. Is this expected behaviour or I need to do some change in the code? Another way is simply by throwing the next song at the player once a certain known time has elapsed. The diagram is wrong. The top GND is only for the speaker. The lower GND is for the power source. In the diagram both are interconnected causing the clicking noise.
Is there a way to set playback to random? Avoid loops however though. Ground loops will act like an antenna to pick up hum noise pops and clicks. Remember that this module has a dirt cheap class D amplifier, so it is never going to sound out of this world like a high-end class AB. I need a stand alone sound module that can play a sound from a trigger on a mobile device to simulate rotational noises of the machine.
The sound would be triggered every revolution and needs to increase with rotational speed. Can this gizmo work that way without the Arduino for a sound. Can someone help me with the code for this?
Motors just have to be on … nothing more. Everything works just fine, which is surprising knowing I received my Elegoo uno r3 only 5 days ago.
The only thing I really need to do now is find a way to retreive data from DFPlayer module to my App. Does anyone know if such thing is possible? Tough luck James, sd card is not accessible through pins on df player board, not impossible I guess, but definitely not easy. I added a function that I use for playing, that accepts a bool Loop and when Loop is true, it loops the audio, otherwise just plays one shot.
I made the same and it is working fine. Thanks for this article.. I have one doubt. Is their a way to detect headphone and disable speaker like it used to happen in phone and laptop. Most devices do this mechanically. When the headphones are inserted it pushes a leaf switch away, and physically disconnects the wire feeding the speakers.

Arduino Basics: Making Sound
Our Pulse Sensor Arduino code is designed to find the moment of heart beat in the pulse waveform for accurate BPM calculation. Once you've done that, navigate to. This example uses the Arduino tone command and will make a nice little beep when your heart beats! Let's lash up the circuit! Follow the Frizing diagram at the top of this page. You can also refer to this schematic of what we're going to do. The LED is connected to Arduino pin 5. This pin will make the LED turn on when your heart beats, then it will fade softly for a nice effect. It is important to use at the very least a ohm resistor. You can use up to 1K, but any less than may result in weird behavior.

Using this project, you can play audio files of specific format that are stored on a microSD Card using Arduino Uno or Mega. Making your own Music Player using Arduino Uno is an exciting little project. Once you have a circuit using Arduino Uno, a microSD Card Module Adapter , a microSD Card and speakers or headphones, you can implement several sound effects in your projects, which are not possible under normal circumstances. The audio files stored in a microSD card more about audio files later are read by Arduino with the help of SD Card Module and played through a speaker. Check out that project first and if possible, try to implement it before proceeding with this project. The following image shows the circuit diagram of the project. Additionally, a speaker is connected to Arduino, but it is not shown in the circuit diagram. As mentioned earlier, the speaker is connected to Pins 9 and GND not shown in the circuit diagram.

Speaker with Arduino
I want my Arduino to play many words about or play music from a pen drive no sd card. You need an audio amplifier of some sort. Small modules are available, for example, this one. The sleeve is the long contact at the base of the connector. They are the left and right audio channels. I hope you help I want that but how to connect my speaker has 3 rings 2 small,1 big ring ,what pin to connect on three pins.
This tutorial is about building a DIY audio player using Arduino. Today audio players can commonly be found across many electronic products. Almost every mobile has an audio player. Audio technology gets a drastic improvement with rapid development in silicon technology. Previously audio data was stored on tape devices and CDs. But now, Flash memories are cheaper, store huge amounts of data, consume less power, and are much faster than CDs and tapes.
One timer is used to generate a high-frequency square wave whose duty cycle corresponds to a particular value amplitude in the audio sample. Another timer is used to update this duty cycle at 8 KHz, the sample rate of the audio. You should still be able to use pins 3, 9, and 10 for digital input and output. The audio signal will be generated on pin
