First off, happy new year. For the new year, I would like to build/get a networked arduino unit that triggers my garage door remote so that I can open and close my garage remotely. What I am basically trying to do is build an arduino unit that wires up to a portable garage door opener/remote and is networked so I can trigger it remotely. I've been doing some research and it looks like I might need to get an arduino uno, ethernet shield, relay shield. Maybe tapping into the connections to the switch on the portable remote and hooking it up to the relay? Looking for assistance on this project. Let me know if you are interested.
You may as well try to reverse engineer the main PC board on the door opener. When you push the remote, the receiving end of that signal has a digital output which you can replicate with a relay controlled by the Arduino. But it may be easier to just wire into the remote's button. You'll need a multi-meter to learn the voltage you'll have to relay, as you probably already understand. Once you know the voltage for the signal, you'll want to find the same value from the source board (garage door remote or main board) or supply your own via a power supply.
You may as well just skip the uno and jump to the Arduino Ethernet. Then you can only contend with the relay shield of your choosing. Youll probably want to set up the Arduino as a web server so you can access changing the state of the output lines.
Both of these links have some basics for changing output states via internet connection.
Another option is to get the GSM shield and you could SMS your way into the garage. Baby steps first tho.
There will be tons more info youre going to need but we as a community would need more info from you to know how to help. Like which model garage door opener do you have?
If this was any help, +1 me.
HNY!
ps- try to start the project your self before offering pay. you may surprise yourself. ... as I get dirty looks from those that like these offers as income.
Most garage openeres have a pushbutton acivator on the unit itself or even a socket for an external keyswitch.
A relay there would be the simplest option
That link has most of what you need and is a good starting point, I'd go further and make a web interface and also add a sensor to tell that the door is actually open or closed, that could be either a hall effect or some something else.
