Simple Circuit Question LED light/ Metal contact Answered
I have two pieces of metal, pretty heavy stuff, probably stainless steel, and was toying of the idea of being able to wire them up so that if they were touched together it would light an LED.
See attached illustration for a general idea of what I am talking about.
I am not sure if this is even possible.
I think I may need to have some pad-style contacts wired to the very edges, so I'm limiting the surface area that is making contact... otherwise it seems like it may need an awful lot of voltage/current to get through all that metal, probably drain batteries fast too...?
Another thought is if the metal were left like it is in the diagram, separated, and if you could bridge the gap with a finger and have it light, that would also be very cool.. just don't know if it's possible.
