I'm building a game where you have to pick and cut the correct wire (out of 8 to choose from) in order to deactivate a 'bomb'.
The wires will be connected between two header sockets such as this (don't know why I missed one out, there should be a wire there):
Does anyone have any ideas as to how I should wire this up?
I'm thinking about maybe measuring the voltage using analog pins but I only have 3 to spare. Ideally, the person setting up the game will be able to choose which wire is the 'safe' wire. If it's easier to wire up I could have a choice of only 3 safe wires.
To clarify, only one wire prevents the bomb blowing up, the others will all activate a digital pin to sound the siren.
