AHA Project RFID Part 2

In this tutorial we will see how we can recognize persons using our RFID reader.
Two LEDs will be added at the project in order to get some better user experience.
A "security line" will be also added. The concept of the "security line" is pretty simple.
If the line get's 5V (is HIGH) then arduino knows that the RFID reader is working correctly otherwise the RFID reader is broken (or the communication between arduino - RFID reader).
As always we will make an "object based" approach.
From the first article of RFID we can find the TAG IDs.

In this tutorial we will see how we can connect a RDIF reader into arduino.
We are going to use a 125 Khz RFID module  that can be bought from seeedstudio.
Some 125 Khz tags are also needed. We bought them from ebay but you can also find them on other online shops.
This guide is the first of a series of articles.
Starting from this article we are going to construct from scratch a home alarm based on arduino duemillanove.
Since the project is big we are not going to see a lot of details of each part / sensor.
In the future we will try to cover the theoretical gap.
These series of tutorials will be easy to understand and will help you to construct step by step the "A-H-A" (Arduino Home Alarm) project.
