Forgive my dumb question, but I'm just starting to mess around with Arduinos and building a circuit using them, and I keep coming across descriptions about using the digital inputs in conjunction with switches... and every description includes a pull-up or pull-down resistor connecting the digital p…

Basic Q: How can you connect a Digital Pin to both 5V and Ground??
