Thanks ad. Like I edited above, it is much faster, just like everyone asked for. Does anyone have any ideas, as to how I could have it test water, salt water, and breakable/broken metal? I personally can't think of any good ways to do it. I would love for it to be able to test them, but I don't know how to make it be able to, the conductive properties conflict with metal and battery. Anyways, hope everyone likes the new sped up version.

yeah, the problem is, so can ptct, and swch can too, so that means that it comes out the same as btry, you can try it in the tester.
