ABSTRACT Smart car deals with the smart collision avoidance between the vehicles using visible light communication. The basic concept behind this technique is that the data can be transferred through LED light by varying light intensities faster than the human eyes can perceive. This technology uses a part of the electromagnetic spectrum that is still not greatly utilized- The Visible Spectrum instead of Gigahertz radio waves for data transfer. Light Fidelity Li-Fi has got a much broader spectrum for transmission compared to conventional methods of wireless communications that rely on radio waves. By Communication through visible light Li-Fi technology has the possibility to change how to access the Internet stream videos receive emails and much more. Security would not be an issue as data can t be accessed in the absence of light. As a result it can be used in high security military areas where RF communication is prone to eavesdropping. By adding new and unutilized bandwidth of visible light to the currently available radio waves for data transfer Li-Fi can play a major role in relieving the heavy loads which the current wireless system is facing. By the use of this technology smart cars have been implemented. Key words Light Fidelity technology Microcontroller Arduino alcohol sensor ultrasonic sensor. Cite this Article N. Selvarani P.
