Hello everyone, I am having trouble finding any information on how to build a very simple wireless switch. I have seen the modules that can transmit serial data and I know these can be used as a simple on/off transmission as well, but size of the reciever must be as small as possible. 25mmx42mm is just too big for what Im working on. Range will only needs be about 6 feet or so and infrared is not an option. Any links to info on this would be great! Thanks, -Jacob
