    M. Math, the Mini can handle two external interrupts with no problem. I am not sure what the maximum frequency is, but we have interrupts at about 200Hz on Int0, and 50Hz on Int1.

    What may cause problems is noise. Noisey input is common, although if you are testing battery voltage, that might not have noise. If you can, look at the input on an oscilloscope. Good luck…
