I'm really new on this Arduino thing, so I don't know whether what I'm gona ask is feasible or not.
I'd like to make a chronometer in the computer but the controlling button (beginning and end of count) not to be some computer key. So I was wandering if I could make a button controlled by the arduino - maybe via a piezoelectric element?
Besides the problem of not knowing what to use as a button, I don't really know if it's possible to make a graphical interface (i know how to programme in C, Python, ...) showing the numbers in the screen of the computer and the beginning and end of counting controlled by that button. Is this possible to do?
Thanks for any help to both questions!
