I'm sorry guys, but I recently had an idea stuck in my head but I don't really know how I would go about this. I was thinking of building a circuit that when you touch some metal piece, would turn on some led lights.
My first impression on how to do this was to have the person touching the metal act complete the circuit (since he is connected to ground (Earth)).
Then I thought a little more about it and I'm not sure how to get this working.
Any ideas/help would be greatly appreciated.
