LIFI Based Two way Data and Audio Communication Electronics Engineering Final Year Project

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.
