I want to create a simple circuit that runs around the Arduino(which sends a small current) and then feeds back into it, and when this happens successfully an attached LED will blink, if the circuit is broken(let's say the wires are not touching somewhere in between) the light will be solid. So the light will tell us if the circuit is off or on. Does anyone know how this could work, is there any program or any certain methods I could use?
If you don't get what I'm trying to say please ask me for clarification.
Thx.
Yes not too clear to me.
Basically do you want to test continuity? If so that is not difficult just look at how a digital push buttion is wired up. Your circuit is that button. Then the code just looks at the digital input and blinks or turns on solid.
Yes, kind of like that, basically if the circuit is broken then the light must turn on, if the circuit is all connected then the light must be off. When I say circuit, all I say is a simple wire that runs in a circle to and from the arduino, when I disconnect the wire from one of the terminals then the circuit is "broken".
