A street light is a raised source of light on the edge of a road or path. Modern lamps may also light-sensitive that activate automatically when the light is or is not needed. Many street light systems are being connected underground instead of wiring from one utility post to another.
In this tutorial, we are going to make one light-sensitive bulb using LDR
LDR is a light dependent resistor which shows a drop in resistance proportional to applied light intensity.
