ABSTRACT: The
latest uproar in this era is about a technology termed as Light Fidelity or
more commonly known as Li-Fi. There are currently two trends being seen: First, the extension or enrichment of wireless
services and other being
increased in
user demand for these services, but the available RF spectrum for usage is very
limited. So the new technology of Li-Fi came into picture, which uses visible light as a source of
communication. Li-Fi is the most recent development which is resourceful. In this technology, LEDs are used to
transmit data in the visible light spectrum. This technology can be compared
with that of Wi-Fi and offers advantages like increased accessible spectrum,
efficiency, security, low latency and much higher speed. This research paper
aims at designing a Li-Fi transceiver using Arduino that is able to transmit
digital data. The hardware has been designed using Eagle CAD (version 7.1.0) tool and Proteus design tool (version 8). The software coding is done
by using Java (version
8). Successful transmission and reception of text, image and video signals is
carried out on the transceiver. Hence this research work gives an innovative way of designing a transceiver which
works by using off the shelf low cost components and using visible light
spectrum.
