I would like to be able to detect a moving object fitted with a transmitter.
The transmitted signal would be by receiver connected to my arduino.
However, I want only to detect specific objects , so the signal would have a unique signature, so I can distinguish whether the moving object is or is not the type I want to identify, and how far it is
Which direction should I take?
P.S: newcomer, with RF kit on its way. I'm currently a baker making 20p profit per loaf, so urgently need a million $ invention
