Night light with transistors

Simple circuit that turns on the light automatically at night

Reading time: <1 minut The project has a simple circuit that turns on the light automatically at night. It is based on 2 NPN transistors (BC547) used in Darlington configuration, and a photoresistor. With the help of a potentiometer, the light sensitivity of the LDR photoresistor can be adjusted.
