For the Mega and Leonardo

If you are using an Leonardo or Mega, you will have to replace the existing SD card library to

add 'SD card on any pin' support. If you have an Uno/Duemilanove/Diecimila, this is not

required.

First, find the "core libraries" folder - if you are using Windows or Linux, it will be in the folder

that contains the Arduino executable, look for a libraries folder. Inside you will see an SD

folder (inside that will be SD.cpp SD.h etc)

In the libraries folder, make a new folder called SDbackup. Then drag the SDfolder into

SDbackup, this will 'hide' the old SD library without deleting it
