A quick and dirty version of what can essentially be a door lock. I have an Arduino connected to an ID-20 RFID tag reader. Long story short, the reader reads the tag and sends it to the Arduino so that it can activate the servo or the appropriate color LED.
Green means pass, red means fail.

I am building the exact same thing with an arduino pro mini. Having some trouble with getting the ID correct every time. What library are you using to handle the serial input?
