Thanks for the help! So with something like http://www.quasarelectronics.com/3129-up-down-4-digit-led-event-counter.htm How would I be able to tweak it to be sensitive enough to respond to skin conduction as a part of the circuit (basically, count a contact with a resistance of over 1k Ohms)?

I need a device with something like a 4-digit LCD or LED display which counts the amount of times its input and output contacts close. Basically, 1 count for each completed circuit. I was told things like these exist and are cheap, but don't know what to call it. Thanks in advance!

Thanks! Also, I read that this can be done with capacitance - connect one plate to the ground of a BNC -> A/D converter, and the other plate to the pin. The signal can then be read as a spike when contact is made between the two plates. the thing is - if I don't have a A/D converter, is it...

A single count should be the mouse making contact (and then moving away) from the 2nd metal sheet (it is always in contact with the first). if the mouse bounces three times, that should register as three counts. How versatile is the software that comes with the multimeters? As a regular computer...

I have a similar question: I'm making an apparatus for my lab's animal behavior experiment where I need the computer to count every time a mouse completes a circuit between two stainless steel objects. Basically, whenever the mouse touches both things at once, I need the computer to add "1" to...
