regulate the voltage going to the lighting kit in proportion to the signal strength received from the rf emitter. Can anyone help? I have absolutely no experience with stuff like this.
It is possible but you would need to find a RFID module with a RSSI (receiving signal strength indicator). You may need to do some research first, on them and shop around.Post any links you find.
RF signal strength probably will not work as expected.
Could be, but why do you say that?
