LDR

A photoresistor is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits, and light-activated and dark-activated switching circuits.

Optical Glove Controller using LDR

“Use an inexpensive Light Dependent Resistor to control servos with a glove interface. A student at the high school where I teach has designed a laser-cut acrylic hand with movable fingers. He wants to control the fingers individually. It occured …
