Hi all, I'm trying to work out how these pins work, and also trying to make sure I don't short out my board or break my new arduino... If I connect an input pin directly to the 5V pin, I assume that the voltage coming into the pin will be 5V. However, if I connect the two pins with a 100 ohm resis…

What will the voltage be at my input pin?

Cool, thanks!
