Instructions:
1. Place the .ino and .h files in a directory under your Arduino sketeches folder named "Open_Access_Control_v4_std" .
2. Place the remaining directories in your Arduino libraries area (usually C:\Program Files (x86)\Arduino\libraries for Windows)
3. Restart the Arduino software if libraries were just added.
4. Connect up the Open Access v4. Allow the system to detect the USB/Serial port. Select "Arduino Duemillanove" from the
list of boards.
5. Change the privilege password in user.h and check other settings as needed.
6. Compile and upload the program.
Changes:
10/15/2013 (Version 1.40)
Ported libraries to work on Arduino Software 1.5 and higher
Removed "Superuser" functions
Removed unused test cases from reader function to save memory.
10/23/2013 (Version 1.36)
Updated the lockall() function to fix bug when relocking all doors (I/O pins high instead of low)
Updated reader code to allow user to define whether or not a reader has a keypad from user.h file
Updated superuser code to disable superusers by default.

From the datasheet:
The AT24C1024B provides 1,048,576 bits of serial electrically
erasable and programmable read only memory (EEPROM) organized
as 131,072 words of 8 bits each. The device’s cascadable
feature allows up to four devices to share a common two-wire
bus.
