Improve this answer. Yes, I did a project yesterday to play recorded voice. You don't need a speaker module. Isuru Walpola 3 3 3 bronze badges.

I am a bit puzzled by your answer because it is specifically about not using external hardware like a shield, but "to play a sound through an output pin".

Thus your answer does not address the question at all. The UDA amp has a built-in 3. The SD Card Lab has notes on how to do this. There are also instructions on the Arduino site on formatting your card, as well as the Adafruit site. You should test the SD card for reading and writing first. Your filename needs to correspond to 8. The ArduinoSound library can only play audio files formatted as.

The ArduinoSound library comes with a and example called WavePlayback to get you started. Here are a few of the important parameters you should know about:. From that, you can get the file duration, sample rate, bits per sample, channels, current time, and more. The AudioOutI2S class gives you control over playback. You can check if the output can play, and you can play, pause, loop, resume, stop the playback. You can also check whether the file is playing or paused and you can set the volume.

At the start of your sketch, import the libraries and set up a variable to hold the SDWaveFile instance like so:. In the setup, you need to check that the components are working. The AudioOutI2S. This will end the setup function:. It will play regardless of what you are doing in the loop function. Can you help me? Can you provide that? I have been struggle with this project for weeks now. I need some sample with. I tried change pin 4 to 10 already since I have read somewhere that UNO needs pin Reply 5 years ago.

Greg April 30, Maks Surguy April 30, Crazy Al May 2, Greg May 4, Hi Maks, Thanks for your reply but i worked it out. Then all I have to do is change one line in the sketch to play my converted wav file and upload. The last file I converted and played was 60 seconds long and sounded great. My sd card is only meg but played it no problems.

I will try a bigger file tomorrow to see how much I can fit on this card. Maks Surguy May 5, Pietro May 15, Marcus May 20, GDK May 26, Togo May 30, Christin David Bose June 3, Maks Surguy June 3, It should work the same way as with MicroSD since they are basically the same thing.

Andy Graham. Maks Surguy June 14, Unfortunately my focus is in a different domain right now… Sorry! TMRh20 June 14, All you need is a minute long wav file and the wav library shown above.

Code: Follow the example sketches to initialize the library, then in the main loop: if! Tony December 3, Raj March 5, Here is the pin connections I found. I have not tried this project yet.

Pasquale Ambrosio July 7, Andres Moks July 8, It was my bad, I had copied it into a wrong subfolder. After long hustle with no success to get WTV to play, my arduino finally plays sounds!
