Hi, I want to do a project to use my iPhone to remote control my car - such as open the door. The problem, I'm not sure if I can use bluetooth to do this. Or use Wifi module. If wifi module, do you have any suggestion which one to use? I searched on the youtube, it seems that many people don't directly connect their iPhone with wifi, but connect to computer at first, this is what I don't want to do. Getting a computer involved for just opening a door is just to stupid. Another thing, because I have to make that module give output to the electrical circuit of my car. Thanks a lot!!
