I'm totally new to Arduino -- I just bought my first kit last week. Please bear with me.
I'm trying to create an extremely simple circuit that will run current through a wire, and detect if and when the circuit is broken. This is probably the easiest project you guys have ever heard of, but right now, I'm having a hard time figuring out how to accomplish it. Right now, I'm thinking out treating the wire like its a switch, and simply checking to make sure that its digital value remains constant at 1, and when it changes to 0, continue with the program.
My main issue is figuring out where I should attach the wires and how I should connect them to the board -- I have an Arduino Uno and a fully assembled Sparkfun "Protoboard", but I cant figure out what else I would need to make the circuit work and where I should attach it.
I would greatly appreciate any insight into what other electronics I need to attach to make this work, and also where I should place then, and I how I would acknowledge this in the code. I'm used to systems like the Handyboard and CBC where we dont have to do a lot of this stuff -- so hopefully you guys can introduce me into the platform and kickstart my Arduino career.
