Ldr Light Sensor Circuit. On the other end connect an led to two parallel pins of breadboard. The circuit of light detector is very simple and easy to build with very few components.
On the other end connect an led to two parallel pins of breadboard. This circuit detects light incident on the ldr and turns on led whenever the intensity of light is greater than a certain level. A voltage divider made using ldr ldr1 and a potentiometer rv1 b output led d1 in our switching circuit made using a transistor bc547 q1.
This makes the voltage at the base of the transistor too low to turn the transistor on.
