Hello electro tech online
I want to build a coin recognition system, I think that it works with something measuring the magneting field that can be let through the coin. I am not sure, but can anyone lead me in a direction of something that can measure resistance of a material without physical touch of the material?
I am on bare ground
thanks in advance
