Note: Unpack the libraries (WIEGAND26, DS1307, PCATTACH) into your arduino

libraries directory.  This is usually:



~/arduino/hardware/libraries/







The hardware design for the Open Access Control for Hacker Spaces uses the Arduino 

board with Atmega 328. It has been tested with:



-Arduino Uno

-Arduino Duemilanove

-Freeduino through hole (NKC)



The software has the following features:

-Shield compatible with Arduino

-Designed for use with Wiegand26 format readers (up to 3 support in software)

-DS1307 Real-time clock support

-(2) Wiegand26 reader inputs (optoisolated)

-(4) Alarm zone monitor ports using Analog0..3

-(4) Relay outputs





The following pin assignments are assumed by this software:



-Pins 2,3 for Reader 1

-Pins 4,5 for Reader 2

-Pins 5,6,7,8 for Relays

-Pins A0,A1,A2,A3 for alarm sensors

-Pins A4,A5 for SDA,SCL (I2C)
