5-min Tutorials - SD Card Reader with Arduino - Code and Test

This is a new series called '5-min Tutorials' to provide quick tutorials on common electronics and arduino based sensors/ devices.
This is a review/ tutorial of the SD card reader for arduino, in this video, i show how to create a file in an SD card using the arduino, how to read a file from an SD card using an arduino, and general usage of SD card with arduinos. For Simple Arduino projects, subscribe to Fungineers!

Hello very good video can you put the code somewhere?
pls

[@-Fikra-qq1zd]

If I use an SD Card Reader with Arduino and esp8266, does it use a common 3.3v voltage for the two, or does each of them connect separately? Thanks

[@ARSHADALI-oz7ou]

Hello Sir!
How should i read onky last line of my sd card text file while using sd card

[@leisryan]

Hello have you done reading files from SD card with arduino from PC ...,it's just like reading from a hard drive?

[@dorubrad]

Why does the adapter have rows of pins? What is the correct row to use?

[@rebecalunardibublitz6358]

Im from Brazil, and man you saved me!! Thanks a lot! Loved the video!!!

[@JassonQuill]

can it read csv files?

[@user-su1bz8yz5l]

hi , i'm trying to get this module run with a servo but can't because of timer problem , plz i need help

[@ernestorivero9909]

Fungineer me gusto su video,pero déjeme plantearle algo a ver si usted me ayuda o le sirve como pie para un video nuevo.Yo descargué el software JINX, vay usted ha oodo hablar de este software,con el se hacen animaciones que luego se guardan en una targeta sd,en los videos que yo he visto sobre este software te enseñan hacer las animaciones y como guardarla en una targeta para que luego sea leída por un arduino nano,uno,o mega,pero que pasa que no te hablan del código que debes descargar en el arduino para que te lea las animaciónes que grabaste en la sd y enviarla a una matrix de led.Seria usted tan amable de orientarme donde buscar un código para programar el arduino y este me pueda leer las animaciones que hay en la memoria sd,le repito animaciones que grabe del software JINX.

good video, thank you

[@whoismatera]

This was uploaded two years ago. Can I still ask questions?

[@w4rh34d1]

Nice tutorial...sir what if button is press and read line by line..at a time. Whats the code added.

[@any123-og]

I have that sd logger but it is velleman

[@PurpleGround]

Cool!

[@priyaranjantiwari1827]

can we Load sketch code from SD Card

[@Afif87123]

Ithink so

[@bigsmoke4663]

Keep the good work up!!!

[@gazzacroy]

cool

[@Jay-ym2ri]

mine says inislising failed

[@jaxxrr]

same

[@bot-sk8mt]

this sd card reader is strange. Mine wouldnt work properly and I tried like 10 differernt things to fix it, but in the end I connected the wires to the first row of pins and then it worked.

[@dorubrad]

First row is the one at the end of the adapter or the one to the inner side?

[@rumrobot_]

My code or piece doesn't work I made the same code as you but there was anything when I plugged it into my pc then I put the if statement at the end of the setup to see if the file exists there but it doesn't?? So in the ending i have this code:
#include
#include
File myFile;
int speakerPin = 8;
void setup() {
pinMode(speakerPin, OUTPUT);
Serial.begin(9600);
while (!Serial){
;
}
Serial.print("Initializing SD card...");
if (!SD.begin(4)){
Serial.println("Initializing failed!");
}
Serial.println("Initializing done.");
if(SD.exists("example.txt")){
Serial.println("example.txt exist.");
} else{
Serial.println("example.txt doesen't exist.");
}
Serial.println("Creating example.txt...");
myFile = SD.open("example.txt", FILE_WRITE);
myFile.write("Hello");
Serial.println("Writing to file succesful.");
myFile.close();
if(SD.exists("example.txt")){
Serial.println("example.txt exist.");
} else{
Serial.println("example.txt doesen't exist.");
}
}
void loop() {
}

[@rumrobot_]

Now I tried it again WITH the example.txt file and it says that it still dosen't exist. What should i do?

[@Fungineers]

Looks like your SD is not being read. Whats the SD card capacity?

[@Fungineers]

Did you see my other video about SD card problems? I discuss some of the common issues

[@rumrobot_]

@@Fungineers its about 4GB

[@rumrobot_]

No, I didn't. but I will look on that ;)

[@kt__23__63]

Can I use 16gb sd card...???

[@Fungineers]

I think 8gb is the limit. But you can try

[@kt__23__63]

@Bitor Bit Dude... 182gb card doesn't exists...

[@GLH8]

Think it needs to be formatted in FAT32, most come preformatted in different formats

[@solodagci]

@@Fungineers Then why do you show a 128GB card in the thumbnail and on the table, near Arduino?

[@solodagci]

Btw. I tested it with my 128GB sd card and it was successful. There's no 8GB limit. You have to make sure to format the card as FAT32 via guiformat tool though. ridgecrop.co.uk/index.htm?guiformat.htm

[@bigsmoke4663]

Its me Kevin kevin

[@guillermotrujillo8282]

no ma wey porque no le pones el link a los archivos de las librearías y de una vez de todo el código, pero ps chido perrito gracias por el tutorial

[@mariafernandamijangos7513]

sabes que ibrerias uso?

[@bbbbbbbbbbbbbbbbbbbbbbba]

hi good.

[@letsgetto1millwithoutvids]

I'd pay you to make me some code that clones an SD card to another 1 to 1 with partitions and everything.

[@pramodjalgaonkar1221]

1 sd card can read 2 Arduino Device

[@jaxxrr]

I spent two hours trying to figure out why it wont work... DO NOT USE 5V on Arduino Uno.. use 3v3 !!

[@indianastones9884]

horrible video: 1. Name your Board 2. Name the Modul= Hw203 3) Show the wiring from above and the the shematic 4) explain your code at least somewhat.
