Garage door opener via mobile phone and rfid.
Using arduino rf to open garage door.
I use sdr radio and audacity to do the hacking and an ad9850 dds and an arduino to create a clone.
Whenever a valid key is swiped the arduino triggers a relay which can then be used to control just about anything.
When the relay closes it connects the terminals of the garage door signal contacts.
Output pins are connected to relays.
Connections are not difficult.
Our own network enabled garage door opener controlled with an arduino.
Using 2 micro controllers 2 boards communicating with a personal protocol it really is over engineered but useful nonetheless.
So we tought about our last project where we successfully made arduino talk with raspy using nrf24l01 and dumbly toggling lights.
If the tag is on the authorized list the arduino will pull a pin high to provide 5v to close a relay.
In this case jason plans to use it to control his garage door.
The garage door then opens.
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.
It was a boring situation where we had to constantly find the remote open the gate wait for them to take their bikes and then open again.
Two digital pins of arduino are initialized as output to control the garage door and light.
Just follow the below simple rule.
Arduino rfid garage door opener.
At the output of relay you can connect your light and door motor main power line.
Well it wasn t so boring but you know we needed a reason.
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.
In this case it will emulate the switch in the wall mounted or portable remote that you currently use to open the garage door.
The arduino then reads the code from the serial connection and compares it to a list of authorized rfid codes.

A relay board to activate the opener this acts like a wall switch or button but the etherten pushes it instead of you.
In this project we will be using the power of rfid to tap into your garage door opening system.
433 92mhz rf transmitter and receiver pair i got mine from ebay for the ridiculously cheap price of 1 45.
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.
