I want to build the garage door opener but I have my own hardware. I plan to use the Arduino UNO or Leonardo board and I also have the ethernet shield and the wifi shield. I would like to use the wifi shield so I don't have to run a cable to my router. I also have a bread board and stand alone relays.
My questions are......
1. Can I use the wifi shield?
2. Can I set it up to control the relay which will just momentarily close the connection that is connected to the door button in my garage?
3. Can I access or operate the garage door from somewhere without being on the same network as the Arduino?
Any help on this is greatly appreciated. I am willing to modify the code if needed but I would need some help on that.
Thanks,
Stew
