Getting started with Adafruit's Micro-SD Breakout Board in 2 minutes.
Wiring
Wiring the Breakout board is very simple.
- Connect the 5v pin to the 5V pin on the Arduino
- Connect the GND pin to one of the three GND pin on the Arduino
- Connect CLK to pin 13
- Connect DO to pin 12
- Connect DI to pin 11
- Connect CS to pin 10

Programming
To use the Micro-SD you need to include the SD.h library at the top of your program. Then add the following line of code to your setup() function:
SD.begin(10);
Now you can write something on the card:
File logFile = SD.open("log.txt",FILE_WRITE);
if(logFile){
logFile.println(“Hello World!”);
logFile.close();
}
Finally, while humming the MissionImpossible theme, you can power off the Arduino board, take the Micro-SD card out, put the micro-SD card in an SD card adaptor, put the SD card adaptor in your laptop and look at your new file.
