Automatic Dim Bright Controller

Abstract

This project is developed for the users to control the operation of the head light of a vehicle. It consists of light sensors, Controlling unit, driver section and relay section. When the light sensor senses light from the rear side, it sends signal to the controlling section. The controlling section analyses the light and accordingly it operates the Headlight Dim and Bright bulbs. Since the Headlight operation is entirely controlled automatically, it is very much used in automobiles. It uses PIC16F73 (28 pin Micro controller). The microcontroller controls the entire operation. The microcontroller program is written in assembly language. This control reduces the man work and the operations are very accurate.
