This library contains two types of class; first one is eeWrite which writes to EEPROM, second one is eeRead which reads from EEPROM. This library and example shows how to use the utility libraries on which the EEPROM library based in order to read and write data to your External EEPROM. Also i wrote a blog post about the circuit, wiring, documentaion and usage details which can be found in this page.
Download this Arduino Library, extract the downloaded zip file and put it in your Arduino Libraries Folder; which is located under your documents folder;
\Documents\Arduino\libraries. After that it will be visible at your Arduino IDE Software; under
File|Examples|Examples from Custom Libraries.
Happy coding :)
