Can a 2.4 GHz sigal detector be made with an arduino. My purpose is to detect signal from wireless camera.
If yes, then what are the parts I will need? Will it be more expensive than the spy cam detectors in the market. My purpose is to make a cheaper one than those in the market.
You would need extra hardware I imagine. As the Arduino generally runs at 16 MHz I don't see how it will detect, on its own, 2.4 GHz.
I figured that much but do you have any idea what will be the components I would need.
Look at the parts in a 2.4 GHz transceiver
