Datasheet

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. If you have a rev B shield, this is

also 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)

Ourside 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. Note that SDBackup

must be outside of the libraries folder in order to effectively 'hide' the SD library.
