Audio Player Using Arduino With Micro SD Card

Please SUBSCRIBE my channel for more projects.........................

Many of People want to interface the SD card with arduino or want some audio output via arduino.

So here is easiest and cheapest way to interface SD card with arduino . you can use the audio output from arduino via a switch or sensor .

you can play any type of sound ,music and recording but that audio will be in to .wav file. If it is in .mp3 or any other audio type then we will convert it into .wav file.

Step 1: Components & ​Requirements

• arduino uno
• micro SD card Adapter module
• micro SD
• Card Reader
• Speaker or earphone speaker
• woofer or amplifier

Step 2: Convert Audio to .wav

Go to the Link to convert the audio into .wav .

http://audio.online-convert.com/convert-to-wav

1. Go to The Link
2. Upload your audio you want to convert to WAV

3. Change bit resolution to " 8bit ".

4. Change sampling rate to " 16000Hz ".

5. Change audio channels " mono " .

6. Click on " Show advanced options ".

7. PCM format " unsigned 8 bit ".

8. Convert file.

At next page click on "direct download link"

Step 3: Prepare SD Card

Download the Zip file and Extract it.

Here you will get the " SD formatter "

install the SD formatter in your PC.

Now, Connect your card with PC via USB card reader.

Open SD card formatter.

Select the drive of sd card then click on format .

In Next Step Open your SD card Drive .

Past the Audio file that we have converted in .wav file

Rename the file to "test.wav".

Step 4: Add Library in Arduino

Open The arduino Software

Click on then Sketch >> Include Library >> Add zip Library

Select "TMRpcm.zip" that is in zip folder.

Step 5: Upload the Codes

Download the code from link below or i have already mentioned in zip file .

Connect your arduino with pc and upload the Codes.

https://github.com/vishalsoniindia/Audio-Player-Us...

Step 6: ​Circuit Connections

Insert the card in micro sd adapter module.

Connect the circuit as given below.

CS ---------------------->> 10

SCK ---------------------->> 13

MOSI -------------------->> 11

MISO--------------------->> 12

VCC --------------------->> +5v

GND--------------------->> Arduino's Ground

Speaker Connection

one pin is in to 9 pin of Arduino and other is GND of Arduino

Step 7: Play the Audio

Now , It's Ready...............................

Click Reset button to play audio every time.

The OUTPUT sound is very Low so you can use woofer or amplifier for batter Output.

can someone help me how to code in arduino
sd card with speaker
and it will play on a specific time everyday
i have rtc and i try to code it but its not running
i try also millis but still its not playing

[harutyunyananna0213]

Hi Dear friends . We have a project with arduino, but it works wrong. We have three Ultrasonic sensors, one CD card and one audioplayer. We need to read the file from CD and send it to the audioplayer everytime at least one of ultrasonic sensors detects movement.
You can see my code below. It doesn't work correct. Please, if it's possible help to find my mistake or suggest me another code.
Thanks a lot for your time.
We’ll be looking forward to hearing from you!

Hooked it up as shown, used a cheap speaker which maybe explains why I don't get anything out of it but white noise.

[vishalsoniindia]

You know answer

[olivertaylorrrr]

Does the micro SD card have to be a certain size? I bought a 64gb micro SD and i put everything together properly (supposedly) and it still wont work.

[ShannonM119]

Yeah, 64GB is too big. I think the Arduino can handle 16GB max.

Asalamulikum sir
Asalamulikum
My project topics simple arduino player and amplifier with lifi so I asked about which programming are use in this arduino and SD chep. Plzz contact me my email ID. Thank you.

[vishalsoniindia]

I already answered of this question, read above tutorial where you find code.

[Ale Varghese Ninan]

Hi , I had done the circuit as shown . I have a doubt can the vcc of the adapter module directly connected to the 5 V of arduino ?

[Avali123]

I got everything exactly the same, copied the code, added the library and checked if the sd card worked, and it does and yet I cant get it to work, what am I doing wrong ?

[yodizf]

Brother...
how to make an SD card for the Murottal Al Quran speaker

[vishalsoniindia]

Very easy...
Play one song from my tutorial and then as same as you can play many songs

[jonatanko666]

i try to make SD card file read on button press and LED blink with delay ....i want to make cosplay laster gun on shot push make laser sound and light on button hold make stronger charging laser sound and im new i try to make some code but almost always have some errors cause im newbe in this and i know i forgot add library or something to make works as shuld and i dont know where to begin and cant find any similar schematic or manual on web any ideas ?

[RyuWhite]

I've been done this with $1 speaker. Sound quality was pretty bad. Any recommendations for speakers?

[PrinceY9]

I have done everything right but the voice is not at all coming from the speaker

[aswtang]

Hi, I managed to get the circuit working and playing music, but I'm struggling to get it to work with a sensor. I want to use a microphone sensor to start the music. I've tried merging this code with code for the sensor, but I'm relatively unfamiliar with Arduino and can't get it to work.

The code I've used is;

#include "SD.h"
#define SD_ChipSelectPin 10
#include "TMRpcm.h"
#include "SPI.h"
const int speaker = 9;
const int mic = A0;
const int threshold = 10;
int sensorReading =0;
TMRpcm tmrpcm;
void setup()
{
pinMode (speaker, OUTPUT);
tmrpcm.speakerPin=9;
Serial.begin(9600);
}
void loop() {
{ // put your main code here, to run repeatedly:
if (sensorReading >= threshold)
{(!SD.begin(SD_ChipSelectPin));
{
Serial.println("SD fail");
return;
}
tmrpcm.setVolume(10);
tmrpcm.play("test.wav");
}
delay(100);
}}

sir i mixed both backgroud music file and a text audio file and converted to wav. After doing all the uploading work ,when i tried to play in the speaker it just sounds buzzz.

But when i tried to play the files individually , it plays
help....i need to play both files in one time......ASAP

[tamias47]

If the two (or more) tracks are always sync'd the same, you could just combine them into a single .wav file using the free program Audacity.

[LiutaurasM]

Heyy, same was to me, i just changed few things, just try to use pin 9 for speaker and also use PROGMEM in this code, it will play more clearlier and moreover for me actually playing :D

/* Example sketch using progmem to store wav filenames. Uses
program memory to store filenames instead of ram when playing
many different wav files.
See http://arduino.cc/en/Reference/PROGMEM for more info.
