or is it just mute?hello sir my name is awan first sorry to interrupt your time, what kind a speaker when you use in this project because from this tutorial I can't rise up my volume and noise everywhere when I play the musicYou can use any speaker, you can also use your computer speakers.Try with a simple speaker first, if you are satisfied remove the small speaker and replace it with a bigger one. Here is what i want, im going to used a toggle switch ( on and off). Let me know please. Especially if you are using an Arduino and you have lots of pins free, you can easily add sound effects to your project by just investing in an extra So to convert any audio file into wav format, follow the below steps:As we know our audio files are saved into the SD card, hence we Now the Arduino will be able to read the music file from the SD card and play it on the pin number 9.

This example shows how to play three songs from SD card by pressing a push button This example code was created for CircuitDigest.com#define SD_ChipSelectPin 4 //Chip select is pin number 4pinMode(2, INPUT_PULLUP); //Button 1 with internal pull up to chage trackmusic.setVolume(5);    //   0 to 7.

Yes you can add a delay after every time the arduino reads the switch No i don't think you will need amplification for Headphones.

Arduino digital pin 9 is the audio output (PWM signal), it’s connected to the audio amplifier. This Arduino project is a simple and fun project you can build in 10-15 minutes. Likewise you can navigate to all four songs.You can also play/Pause the song by pressing the button connected to pin 3.

Please help us if possible! But yes it should work even without a SD card moduleHi, I am looking to build something like this, but with an option to play one of four .wav files. When the button is press again the button will be open and the music will stop. I assume the Amplifier was heating mostly because of a wrong connection. If you are looking for more volume use a more powerful audio amplifier circuit The errors occurred in the code given above is due to music.play() function typecasting is required in this functionYes cyrille you can also use LM358/LM741 as an amplifier but LM386 has a high gain and will work perfect for an audio amplifier.

Now you can press the button again to change your track to the next song that is to play 2.wav. or the sampling of my wav files?hello, i just want to us if it is possible to control the speed of the stepper motor using the music mp3 plays? Thanks!Hey!! thanks!Increasing the operating voltage of the Op-amp will help.

Audio amplifier ground must be connected to Arduino ground (any GND pin). I think that way you filter out also desired frequencies. Step 3: Prepare SD Card. To connect a speaker to the board you have add an amplification circuit connected between the DAC0 pin and the speaker.
You can just hear some noise, buttons do nothing, Whats the problem?hlo, I have tried all the things u have mentioned in ur list. I am thinking to revise the code, but this time using only a single button to turn on and off the music. It consists of a speaker, a simple transistor acting as an amplifier, and a micro-SD card adapter for a micro-SD card that holds the .wav files. It can withstand a maximum of 15V.


Are you getting wired sounds? Download the Zip file and Extract it. Hi I had one other comment but it has not posted yet so please disregard it. Make sure the button is working properly The code has a "}" in the wrong place. The can be either because of your connections or because of your moduleHi. I used the one given here and dint find any problem? Pause an audio File:. A .wav file named "test.wav" is in the card's root directory. Do both buttons have a connection to GND and then to the pins 2 and 3 respectively? The other pins are left unconnected. When the button is closed(permanently closed) ,the music will play. So try replacing the IC, incase if you dont have one ignore the amplifier part they will still work just fine but sound will be low. What's the purpose of putting a 10k resistor in series with a 10uF capacitor to ground at the output? But still LM358/741 will also work I did everything on this page my professor checked it and said its good but when i power it on nothing happens.Not everyone (even the experienced)  gets a circuit to work in the first try. So break the circuit into smaller parts and check where the output is messing up.In this case bypass the amplifier section and connect the speaker directly to check if you are getting any audioNot everyone (even the experienced)  gets a circuit to work in the first try.

To pause an Audio file, you can simply call the line below. many thanksI have not tried it yet. There is nothing special with the speaker, because I have tried it with other speakers and was able to achive the same qulaity.The part list says you need a 10uF and 100uF capacitor but the diagram shows 1uF and 10uF in the circuit....which is the correct combination?I have tested the circuit will both the combinations and they worked fine. Learn to debug a circuit when you don't get an output, this is an important skill in electronics. Because yet we are getting the same message.Yes you can also use a lm358 in place of lm386. Higher music volumes tend to affect the quality of the audio, hence use hardware control when possible.After programming your Arduino simply press the button connected to pin 2 and your Arduino will play the first song (saved as 1.wav) for you.
