/*
* Open Source RFID Access Controller - MINIMAL HTTP EDITION
*
* 11/27/2011 v0.01
* Last build test with Arduino v00.22
*
* Based on Open Source RFID Access Controller code by:
* Arclight - arclight@23.org
* Danozano - danozano@gmail.com
* See: http://code.google.com/p/open-access-control/
*
* Minimal HTTP Edition by:
* Will Bradley - bradley.will@gmail.com
* See: https://github.com/zyphlar/open-access-control-minimal-http
*
* Notice: This is free software and is probably buggy. Use it at
* at your own peril. Use of this software may result in your
* doors being left open, your stuff going missing, or buggery by
* high seas pirates. No warranties are expressed on implied.
* You are warned.
*
*
*
* This program interfaces the Arduino to RFID, PIN pad and all
* other input devices using the Wiegand-26 Communications
* Protocol. It is recommended that the keypad inputs be
* opto-isolated in case a malicious user shorts out the
* input device.
* Outputs go to relays for door hardware/etc control.
*
* Relay outpus on digital pins 6,7,8,9
* Reader 1: pins 2,3
* Ethernet: pins 10,11,12,13 (reserved for the Ethernet shield)
*
* Quickstart tips:
* Compile and upload the code, then log in via serial console at 57600,8,N,1
*
