Garage Door Opener Arduino Uno Rfid

V1 2 shields 2 pin antenna rev 1 2 printed on the board will need the following code.

Garage door opener arduino uno rfid.

The arduino acts as the brains of the operation while an off the shelf nfc rfid reader module is used to read the rfid tags. To add new keys to the system jason simply swipes his master rfid. The garage door then opens. The robotgeek rfid garage door opener kit comes with the rfiduino v1 2.

If the tag is on the authorized list the arduino will pull a pin high to provide 5v to close a relay. We already had one door opener so for the same price we went about building our own network enabled garage door opener with an arduino. The arduino then reads the code from the serial connection and compares it to a list of authorized rfid codes. In this project we will be using the power of rfid to tap into your garage door opening system.

A freetronics etherten or other network capable arduino board this is the brains of the operation. It hosts the web page you connect to when you want to open the door and triggers the garage door opener via the relay when the correct password is entered. Initialize an rfiduino object for hardware version 1 2. V1 1 shields 4 pin antenna no version number printed on the board will need the following code.

When the relay closes it connects the terminals of the garage door signal contacts. We are going to bridge a connection in the opener switch via a robotgeek relay board initiating the door opening as if you had pressed the button.
