But, I have also explained the ability of the TMRpcm library below.

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 SD card module and a normal speaker.

In this article I will show you how easy it is to Play musicadd sound effects using your Arduino Board.

Thanks to the Arduino community who have developed some libraries to build this in a fast and easy way.

We have also used IC LM386 here for amplification and noise cancelation purpose.

Now, since this code could only read.wav files, technically this project cannot be called as an Arduino Mp3 Player, but hey you will still be able to hear songs with it.

If you are looking for simple alternatives like an Arduio music player without SD card, you should check out the Arduino melody player which we have built earlier.

Or else to play mp3 files in arduino, there are websites which you can be used to convert any audio file on your computer into that specific WAV file.

You can toy around with the settings later, but these settings were experiment to be the best in quality.

Once done it should look something like this in the below image.

Similarly you can select any of your four audios and save them with names 1, 2, 3 and 4(Names should not be changed).

I have converted four songs and have saved them as 1.wav, 2.wav, 3.wav and 4.wav like shown below.

The Arduino and SD card communicate using the SPI communication protocol.

Hence the Module is interfaced with the SPI pins of the Arduino as shown above in the diagram.

But the audio signals produced by the Arduino on pin 9 will not be audible much.

Hence we amplify it by using the LM386 Low voltage Audio amplifier IC.

If you want to increasedecrease the sound you can increasedecrease the voltage provided to this pin.

Learn more about this 200 gain amplification configuration for LM386 here.

These switches are used to play the next track of the song and playpause the music respectively.

Insert the card into your SD card module and follow the steps below.
