Using Arduino Rf To Open Garage Door
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.
Using arduino rf to open garage door. 433 92mhz rf transmitter and receiver pair i got mine from ebay for the ridiculously cheap price of 1 45. In this project we will be using the power of rfid to tap into your garage door opening system. In this video i re engineer a 40mhz garage door opener and build a small one for my harley. The garage door then opens.
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. 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. Two digital pins of arduino are initialized as output to control the garage door and light.
Project tutorial by dtbaker. Just follow the below simple rule. 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 jason plans to use it to control his garage door.

When the relay closes it connects the terminals of the garage door signal contacts. If the tag is on the authorized list the arduino will pull a pin high to provide 5v to close a relay.
The arduino then reads the code from the serial connection and compares it to a list of authorized rfid codes. Arduino rfid garage door opener. At the output of relay you can connect your light and door motor main power line. Garage shutter door and light are activated by user.
So we tought about our last project where we successfully made arduino talk with raspy using nrf24l01 and dumbly toggling lights. Whenever a valid key is swiped the arduino triggers a relay which can then be used to control just about anything. I use sdr radio and audacity to do the hacking and an ad9850 dds and an arduino to create a clone. Arduino i m using an arduino uno rev3.
Our own network enabled garage door opener controlled with an arduino. Output pins are connected to relays.
