RFID Garage Door Opener

[Jason] really wanted to build an RFID controlled garage door opener and decided to turn to Arduino to get the job done. For someone who’s never worked with an Arduino before, he really seemed to know what he was doing.

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 key. An indicator LED lights up and a piezo speaker beeps, letting you know that the system is ready to read a new key. Once the new key is read, the address is stored on an EEPROM. From that point forward the new key is permitted to activate the system.

Whenever a valid key is swiped, the Arduino triggers a relay which can then be used to control just about anything. In this case, [Jason] plans to use it to control his garage door. The system also has a few manual controls. First is the reset button. If this button is held down for two seconds, all of the keys from the EEPROM are erased. This button would obviously only be available to people who are already inside the garage. There is also a DIP switch that allows the user to select how long the relay circuit should remain open. This is configurable in increments of 100ms.

For now the circuit is wired up on a couple of breadboards, but it might be a good idea to use something more permanent. [Jason] could always take it a step further and learn to etch his own PCB’s. Or he could even design a board in Eagle CAD and order a real printed board. Don’t miss the video description of the RFID system below.

Wi-Fi Enabled Garage Door Opener

Normally, internet-controlled household devices are a cobbled together mashup of parts. This is great for a prototype, but if you’re looking for something that will last a decade in your garage, you’ll need something a little cleaner and more robust. [Phil]‘s Internet-enabled garage door opener is just that, replete with a custom-made enclosure for his Arduino powered system.

The main hardware for [Phil]‘s build is a Freetronix EtherTen, an Arduino clone with a built-in Ethernet interface. Aside from that, the electronics are simple: a relay, transistor, and diode provide the connection from the EtherTen to the garage door opener.

The software for this setup consists of a main file that sets up the web page, the serial monitor, and loops through the main program. There are a bunch of classes for initializing the web page, writing passwords to the EEPROM, activating the door, and setting the MAC and IP addresses.

Opening the door with this remote is a snap: with any WiFi enabled smartphone or tablet, [Phil] only needs to log onto his network, surf on over to the page hosted on the Arduino, and enter a password. From there, opening the door is just a press of a button. Passwords and other configuration settings cane be entered with MegunoLink. This software also includes a serial monitor to log who opened the door and when.

It’s an interesting and compact system, and handy to boot. You might sometimes forget your garage door opener, but we’re thinking if you ever find yourself without your phone, a closed garage door is the least of your problems.
