Secure arduino remote control garage door opener dec 18 2013 06 18 pm i want to build a device that i can wire into the 12v accessory line of my car that acts as sort of an active rfid tag.
Arduino garage door opener rf.
I have a garage door opener that i got when i moved into my condo.
Our own network enabled garage door opener controlled with an arduino.
However i only have one and we have three vehicles in total 1 car 2 mopeds.

A complete cycle will follow these steps.
Arduino raspberry opening gate and garage doors with arduino 433mhz module 433mhz module attached to the arduino recently it happened frequently that some of our friends needed to take their bikes inside our garden after a nerding night.
I have tried sniffing the 433 92 mhz radio frequency and i found the signal.
The arduino then reads the code from the serial connection and compares it to a list of authorized rfid codes.
If you re transmitting to or on the same frequency as a garage door opener rc toy etc that you bought in your own country it should be fine provided you stick to the power limit.
I want to permanently have a garage door opener mounted on the mopeds and i want to clone one of the opener remotes.
433 92mhz rf transmitter and receiver pair i got mine from ebay for the ridiculously cheap price.
If the tag is on the authorized list the arduino will pull a pin high to provide 5v to close a relay.
The garage door then opens.
Check out this project on.
Garage door opener via mobile phone and rfid.
Using 2 micro controllers 2 boards communicating with a personal protocol it really is over engineered but useful nonetheless.
For the secure garage door opener example shown here we are going to do something very similar to example 6 in the arduino library.
