Arduino Garage Door Opener with Adafruit WiFi Shield?
I was hoping to be able to start my WiFi Garage door opener, but I then realized (Well Adafruit told me (http://forums.adafruit.com/viewtopic.php?f=31&t=44626&p=225993#p225993
)) that their WiFi shield doesn't accept incoming connections :(. They did, however, say that I could use it to set up a UDP server and then send a UDP packet from my phone. Only problem is, I don't know what a UDP server is, or what UDP stands for, as I am extremely new to electronics. My question is, how would I go about doing something like this? Should I just scrap the Adafruit route or is it still relatively simple to do it this way. I am open to all ideas and I don't mind buying another WiFi chip if need be.
