Abstract

The ability to own a vehicle increases the rate of usage on the road. Many accidents occur especially on highways due to the distance of vehicles that are too close to each other. If the driver in front of the car slows down or applies the brakes, the following vehicle driver finds it difficult to manage his car, resulting in a collision. In order to reduce road accidents in Malaysia, a car accident alert system is vital as a warning to the driver before the crash. This system is also important to flatten the curve rate of fatalities on road accidents in Malaysia. This project aims to design vehicle accident alert by using Visible Light Communication (VLC). As Malaysia is geographically located on the equatorial line and is receiving plenty of sunshine over the years, the VLC Technology is suitable for this system. So, the proposed project is hoped to save the development cost. The project is divided into four main parts comprises input (distance), microcontroller (Arduino Uno), Li-Fi transmitter and Li-Fi receiver part and output. The microcontroller acts like a brain that reads the input or signal from the Ultrasonic sensor. Then, the Li-Fi transmitter and Li-Fi receiver will make a data transfer by using light. Lastly, the microcontroller will operate to activate the buzzer as an alarm alert in this project.
