Abstract

Headlight dimmer system has been evolving since it was first introduced but the evolution of this system is still small compared to the evolution of engine, Global Positioning system, and audio and visual system on the vehicle especially cars. The headlight system nowadays still relies on the ‘Dimmer switch’ that needs to be adjusted manually by the driver. So, an automatic system that can change the dimmer switch is the answer. This project is based on headlight that could be changed from high-beam to low-beam or vice versa and switching on and off the fog light automatically according to visibility. For this project, the idea is to invent the lowcost automatic dimmer. To make it cost-low, this system will be designed based on PIC microcontroller technology. So, the objective of this project is to introduce the low-cost Automatic Headlight Dimmer System using PIC microcontroller and also to design a sensor circuit that can monitor visibility on the road and make the dimmer switch change accordingly. After achieving the objectives than only we can implement this invention into our national car industry. But before taking a big step into it, we need to start from making literature review on light sensor as it is very crucial part in this system. Without sensor performing at its best, for sure, this system cannot perform as it is required to work. This system was designed using MPLAB for the software and Proteus for the hardware simulation. The design is ready to be downloaded if there is no error occurred in simulation. This system can be implemented in the national car industry for its low cost.
