/*
* IRhashdecode - decode an arbitrary IR code.
* Instead of decoding using a standard encoding scheme
* (e.g. Sony, NEC, RC5), the code is hashed to a 32-bit value.
*
* An IR detector/demodulator must be connected to the input RECV_PIN.
* This uses the IRremote library: http://arcfn.com/2009/08/multi-protocol-infrared-remote-library.html
*
* The algorithm: look at the sequence of MARK signals, and see if each one
* is shorter (0), the same length (1), or longer (2) than the previous.
* Do the same with the SPACE signals. Hszh the resulting sequence of 0's,
* 1's, and 2's to a 32-bit value. This will give a unique value for each
* different code (probably), for most code systems.
*
* You're better off using real decoding than this technique, but this is
* useful if you don't have a decoding algorithm.

/**
* RFID Access Control Single
*
* This project implements a single stand-alone RFID access control
* system that can operate independently of a host computer or any
* other device. It uses either an ID-12 RFID reader module from ID
* Innovations or an RDM630 RFID reader module from Seeed Studio to
* scan for 125KHz RFID tags, and when a recognised tag is identified
* it toggles an output for a configurable duration, typically 2
* seconds. The output can then be used to control a relay to trip an
* electric striker plate to release a door lock.
*
* Because this project is intended to provide a minimal working system
* it does not have any provision for database updates to be managed
* externally from a host, so updates to the accepted cards must be
* made by changing the values in the code, recompiling the program,
* and re-uploading it to the Arduino. It does however report card
* readings (both successful and unsuccessful) via the serial
* connection so you can monitor the system using a connected computer.
*
* Some of this code was inspired by Tom Igoe's excellent RFID tutorial
* which is detailed on his blog at:
* http://www.tigoe.net/pcomp/code/category/PHP/347
* And also from the ID-12 example code on the Arduino Playground at:
* http://www.arduino.cc/playground/Code/ID12

/**
* RFID Access Control Single
*
* This project implements a single stand-alone RFID access control
* system that can operate independently of a host computer or any
* other device. It uses either an ID-12 RFID reader module from ID
* Innovations or an RDM630 RFID reader module from Seeed Studio to
* scan for 125KHz RFID tags, and when a recognised tag is identified
* it toggles an output for a configurable duration, typically 2
* seconds. The output can then be used to control a relay to trip an
* electric striker plate to release a door lock.
*
* Because this project is intended to provide a minimal working system
* it does not have any provision for database updates to be managed
* externally from a host, so updates to the accepted cards must be
* made by changing the values in the code, recompiling the program,
* and re-uploading it to the Arduino. It does however report card
* readings (both successful and unsuccessful) via the serial
* connection so you can monitor the system using a connected computer.
*
* Some of this code was inspired by Tom Igoe's excellent RFID tutorial
* which is detailed on his blog at:
* http://www.tigoe.net/pcomp/code/category/PHP/347
* And also from the ID-12 example code on the Arduino Playground at:
* http://www.arduino.cc/playground/Code/ID12
*

My first blog
Hello , this is my first blog
And I am an electrical engineer, but interesting in Apple products, especially their notebook line.
I have an 4 year old iBook G4. And dreaming to have Macbookpro 15".
I am a member of apple macintosh fans forum i.e : http://www.macclubindonesia.com/ and http://www.mac.web.id/ all this forums based in Indonesia my beloved country.
Recently Apple had launched their new product which is called Mac book air
