A photoresistor / light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. A photocell changes (also called a photodetector, photo resistor, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (e.g. when light in the room turns on)
