The main aim of this project is to design a vehicle accident prevention system using Arduino and IR sensors. Growth in population has led to growth in technology. People use car on large number and number of accidents taking place, is increasing day-by-day. Road accidents are undoubtedly the most frequent happening cases and overall, the cause of the most damage. There are many dangerous roads in the world like mountain roads, narrow curve roads, T roads. Some mountain roads are very narrow and they have many curves. The problems in these curve roads are that the drivers are not able to see the vehicle or obstacles coming from another end of the curve. If the vehicle is in great speed, then it is difficult to control and there are chances of falling off a cliff. Hence there is a need of many road safety systems. To avoid these problems in curve roads of mountain areas, we have proposed this vehicle accident prevention system. The main controlling device of the project is Arduino UNO Microcontroller. This project makes a use of IR sensors, green and red LED lights. When two cars pass from the opposite side of a mountain curve the IR sensor senses the car and process this signal to the microcontroller then the microcontroller turn on the RED LED which can gives the indication of oppositive side of the vehicle along with Buzzer. And then it changes one LED color into green to allow the one car to pass and then the other LED color turns green. In this way we can prevent the accidents of curved road. To achieve this task Arduino loaded program written in embedded C language.

The main objectives of the project are:

1. Design a vehicle accident prevention system using IR sensor.
2. Green, RED LED indications.
3. Audible alerts using Buzzer.

The project provides exposure to the following concepts:

1. IR sensor characteristics.
2. Interfacing Buzzer to the microcontroller.
3. Embedded ‘C’ programming concepts

The major building blocks of this project are:

1. Adapter Power Supply
2. Arduino UNO micro-Controller.
3. IR sensors.
4. Green, Red LED indicators.
5. Buzzer.

Software’s used:

1. Arduino IDE Studio compiler for Embedded C programming.
2. Express SCH for Circuit design.
