Lifi Based Two Way Data And Audio Communication

DOWNLOAD ABSTRACT

AIM:

Design and development of LIFI based two way data and audio communication.

PURPOSE:

LIFI is an advanced technology and can stream data and audio through light. LIFI nothing but light fidelity. It can transmit light waves with more speed which are in Giga bytes.  We can transmit both data and audio through single LIFI module. Also we can do two way data communication. Here the projects title is LIFI based two way data and audio communication using Arduino.

DESCRIPTION:

LIFI module interface with Arduino UART port and Arduino communicate with each other through RS232 communication. LIFI module has both solar panel and LED array. Also it has amplifier to play audio data.

WORKING:

In this project we are using two sections.  Each section acting as transceiver, means can receive and transmit data and audio. LIFI module has mode selection switch to select data mode and audio mode. Two sections connected with laptop or pc through serial cable. By entering data in serial terminal data will be transmitted and displayed on LCD at other side. Same thing happen in both the sides. Like this audio will be transmitted through LIFI and play on receiver side speaker. Both data and audio communication happen through both the sides.
