[dorkbotpdx-blabber] Arduino - reading digital pins as a number?

[Hans Lindauer]

"A pin may also be configured as an INPUT with pinMode, and subsequently 
made HIGH with digitalWrite, this will set the internal 20K pullup 
resistors, which will /steer/ the input pin to a HIGH reading unless it 
is pulled LOW by external circuitry. "
