current from body?

hi all, just experimenting with my new arduino. is it possible for some current to go from my fingers to the digital ins? enough to trigger a "HIGH" value?

i have a basic pushbutton test, which now works fine, and one lead going from my bread board to a digital input pin. if i touch this wire anywhere near the board of the lead, the program fires as if the value of the input pin in high. so just asking.


Yes thats possible, especially if you do not have apropriate pull up/down resistors hooked up with your switch.
