Raspberry Pi Bsed Bi-directional Li-fi Communication For Transmitting Data, Audio And Image Information
Also Available Domains WSN|Embedded with Matlab
Abstract
This project presents a Raspberry Pi-based bi-directional Li-Fi (Light Fidelity) communication system designed to transmit both digital text and analog audio signals using visible light. Each communication node comprises a Raspberry Pi, an LED for transmission, and a photodiode for reception, enabling two-way data exchange without relying on radio frequencies. Text is modulated and transmitted by rapidly switching the LED on and off, while audio signals are directly coupled into the light source using amplitude modulation techniques. At the receiver end, the photodiode detects the light variations, and the Raspberry Pi decodes the digital data for display and processes the analog signal for audio output through speakers or headphones. This system demonstrates the potential of Li-Fi technology as a secure, interference-free, and energy-efficient alternative for short-range wireless communication, suitable for real-time data and audio transmission in modern smart systems.
