 Switching between GND and digital pin is the default solution used by this library. External pull-up resistors can be added if desired, but the internal pullups should be sufficient for most applications. What might be of consideration is providing sufficient wetting current to overcome switch contact oxidation.

+A set of connections are shown where 0.1μF capacitors are optionally added to provide the following benefits:
 
 - contact wetting current
 - hardware signal filtering 
 - beneficial for interrupt applications
 - improves noise immunity when using longer cables 
 
-Connections shown below are for 3-position switches, both without and with capacitors installed. Note: Connections for basic SPST or SPDT buttons or switches requiring only 1 input are similar and not shown.
