Hi...i am creating a cable continuity tester. I am sending 5v (I can add a regulator to slim that down to 3.3v) down one side and if it reaches the other end I want to change my LED light from red to green. Does that make more sense/Is that something I can do with a Raspberry Pi/Will I need an ADC?
