LDR based Automatic Street Light using Microcontroller

Street light or flood light which is completely automatic makes life easy. Nowadays powerful LEDs are using as flood lights. They have many advantages over old lights like least power consumption, long life, DC operated etc. As they work on DC therefore we can directly use them with batteries without any AC DC conversion losses. Lets see how to […]
