Uncompress and rename the uncompressed folder SD. Check that the SD folder contains SD.cpp

and SD.h

Place the SD library folder your sketchbook libraries folder. You may need to create the libraries

subfolder if its your first library. For more details on how to install libraries, check out our ultra-

detailed tutorial at (http://adafru.it/aYM)http://learn.adafruit.com/adafruit-all-about-arduino-libraries-

install-use (http://adafru.it/aYM)

Once installed, restart the IDE. Then open up the Adafruit_GPS->shield_sdlog sketch and upload

it to your Arduino.

If you're using a Leonardo, uncomment the line

// while (!Serial);

in the top of the Setup() function - this will help make debugging easier.

If you are using an Uno/Duemilanove/Diecimila or compatible, Find these two lines

if (!SD.begin(chipSelect, 11, 12, 13)) {

//if (!SD.begin(chipSelect)) { // if you're using an UNO, you can use this line instead

And comment out the first one and uncomment the second one.

Make sure you have the switch set to Soft Serial and open up the serial monitor and check that

you're connected at 115200 baud (or you'll get gibberish)
