by BARRAGAN <http://barraganstudio.com>

This schematics shows how to connect a photoresistor to a Wiring analog or binary input pin. The pthotoresistor is a variable resitor that changes its resistance according to the light intensity. It can be used to sense light intensity. Typical value for the resitor r is 1K Ohms.
