Garage Door Opener Arduino Uno Rfid

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.

Garage door opener arduino uno rfid.

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. 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. This code will work for any digital output device such as relays leds buzzers and more.

If the tag is on the authorized list the arduino will pull a pin high to provide 5v to close a relay. To add new keys to the system jason simply swipes his master rfid. The arduino then reads the code from the serial connection and compares it to a list of authorized rfid codes. We were quoted 50 for new garage door openers.

The robotgeek rfid garage door opener kit comes with the rfiduino v1 2. V1 1 shields 4 pin antenna no version number printed on the board will need the following code. Members could open the garage door using an android app on their mobile phones or by typing their unique pin numbers into a special website. 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.

When the relay closes it connects the terminals of the garage door signal contacts. The garage door then opens.
