Sample Code

How to install Library? Open the sample sketch "CardInfo"in the Arduino IDE. As you can see, it include the SD library called SD.h, you could also download other open source library on the web.
/* SD card test

This example shows how use the utility libraries on which the' SD library is based in order to get info about your SD card. Very useful for testing a card when you're not sure whether its working or n ot.

The circuit * SD card attached to SPI bus as follows:
** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila ** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila ** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila ** CS - depends on your SD card shield or module.
