Using Arduino Rf To Open Garage Door

So we tought about our last project where we successfully made arduino talk with raspy using nrf24l01 and dumbly toggling lights.

Using arduino rf to open garage door.

In this project we will be using the power of rfid to tap into your garage door opening system. A relay board to activate the opener this acts like a wall switch or button but the etherten pushes it instead of you. Using 2 micro controllers 2 boards communicating with a personal protocol it really is over engineered but useful nonetheless. At the output of relay you can connect your light and door motor main power line.

Arduino i m using an arduino uno rev3. In this case jason plans to use it to control his garage door. Output pins are connected to relays. The arduino then reads the code from the serial connection and compares it to a list of authorized rfid codes.

When the relay closes it connects the terminals of the garage door signal contacts. Well it wasn t so boring but you know we needed a reason. I use sdr radio and audacity to do the hacking and an ad9850 dds and an arduino to create a clone. 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.

433 92mhz rf transmitter and receiver pair i got mine from ebay for the ridiculously cheap price of 1 45. Our own network enabled garage door opener controlled with an arduino. In this case it will emulate the switch in the wall mounted or portable remote that you currently use to open the garage door. 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.

If the tag is on the authorized list the arduino will pull a pin high to provide 5v to close a relay. Just follow the below simple rule. In this video i re engineer a 40mhz garage door opener and build a small one for my harley. The garage door then opens.

Whenever a valid key is swiped the arduino triggers a relay which can then be used to control just about anything. Garage shutter door and light are activated by user. 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. Arduino rfid garage door opener.

Garage door opener via mobile phone and rfid. Two digital pins of arduino are initialized as output to control the garage door and light.
