Introduction:

Street light or light pole is a raised source of light on the road.
Many lamps have light sensitive photocells, that activate the lamp automatically, at times when there is little to no ambient light, such as at dusk, dawn, or at the onset of dark weather conditions.

We have connected the positive terminal of the yellow LED, with pin number 11, and negative terminal with the ground pin of Arduino.
LDR module has three wires, connect the red wire with the 5 volt pin, black wire with the ground pin, and yellow wire with pin A0 of Arduino.
A0 is used to read the analog output.

I hope you enjoyed the video, and learned something from it.
