Will grounding the reset pin for a large amount of time damage a Arduino in any way?
Thanks
Probably not, but I wouldn't advise it!
A long time is relative, if all the reset pin is looking for is a falling signal.
Keeping the reset pin grounded for an extended period of time shouldn't "hurt" the Arduino, but of course, it will be non-functional while it's in this condition.
Why not use one of the hardware interrupt pins for the trip-wire instead?

It doesn't really make a lot of sense holding the reset pin low for twenty minutes.
I think I would trigger the reset pin, then put a timer in the loop(), and if you need it, a software reset of the Arduino when the required amount of time has been reached.
I agree with Bill, interrupts would be even better!

It's for a prank so I only want the Arduino to run once when the Reset pin is "de-grounded"
Thanks everybody
OK, you can't ask this and leave us hanging. Whats the prank? And we'll need a video when its sprung. ?

Won't be able to do a video though. ?
Not my video, but I think it was the same sketch that I am using.
One of my favorite anthems. Just the music. 🙂 I had to learn the song for a history assignment back in high school. I forgot the words but remember the turn. Every time I hear a Russian accent, I play it in my mind. A child of the cold war.
Well if that is the case, forget resets and interrupts. One HC-SR501 PIR should do the trick, and that should be as irritating as one of those singing fish you could buy about twenty years ago!
Oh, and I forgot!
