Hey Blue,
I may have explained it poorly, but the idea was to have a limited range on the RF signal, and then just detect signal strength. I'm not exactly sure how that is done yet, but I think the idea was that the receiver would detect the incoming signal and once it trips a "threshold" then the MCU sees that it has enough strength and the lights begin to turn on.
The thing I am trying to figure out is whether the MCU is sending out "Data" letting the other MCU know that two other devices are in range.
Someone on another page suggested just having two receivers in each device hooked up in series so each have to have a strong signal in order to "trip the switch". This is an interesting solution as it doesn't involve any MCU's, but I think I need the MCU's there anyway to control the lights.
So basically, I'm trying to get a straight answer as to what is the best solution, which schematic to begin with, and if the MCU's are detecting frequency, ID's, or something.
