What Is the Function of an LDR? | Reference A light dependent resistor, or LDR, varies resistance in a circuit based on how much light shines on it. When fully illuminated, the LDR has no resistance and current flows freely, but with darkness the resistance increases and current flow stops. In most circuit designs, the LDR acts like an on off switch based on how much light shines on it. Light Dependent Resistor LDR | Photoresistor | Earthbondhon Electronic symbol.
