Description
SD Card Module simplifies and simplifies your SD application. It connects to the Arduino sensor shield module easily as a peripheral. You can read and write to the SD card with Arduino through programming. SD Card may also be utilized to make development easier, such as for MP3 players and MCU/ARM system control.

Format Your SD Card
You will need an SD Card. The format that SD Card using Windows to a FAT32 volume.
Connect the Arduino SD Card Module to your Arduino
as you saw in the pinout section above please connect the module accordingly you can connect the module to the VCC using 3.3 or 5 volts the 5 volts is connected on the module using an onboard regulator
Simple code to be sure that the SD card Reader is working:
#include#include int cs = 10; // Set chip Select to pin ten void setup() { // Open serial communications and wait for port to open: Serial.begin(9600); while (!Serial) { } Serial.println("Initializing SD card..."); Serial.println(); pinMode(cs, OUTPUT); // Documentation says you're supposed to do this // even if you don't use it: pinMode(SS, OUTPUT); // see if the card is present and can be initialized: if (!SD.begin(cs)) { Serial.println("SD did not initiliaze"); while (1) ; } Serial.println("SD initialized."); } void loop() { }
