Digital Pins. The pins on the Arduino can be configured as either inputs or outputs. This document explains the functioning of the pins in those modes. This can be done by adding a pullup resistor (to +5V), or a pulldown resistor (resistor to ground) on the input. A 10K resistor is a good value for a pullup or pulldown resistor.
