Automatic Street Light Control System using LDR & Transistor BC 557 I Tinkercad Design
Features:
It is a simple and powerful concept, which uses transistor (BC 557 PNP) as a switch to switch ON and OFF the street light system automatically.
It automatically switches ON lights when the sunlight goes below the visible region of our eyes. (e.g in evening after Sunset).
It automatically switches OFF lights when Sunlight fall on it ( i.e on LDR ) e.g in morning, by using a sensor called LDR (Light Dependent Resistor) which senses the light just like our eyes.
