Abstract

Communication is an essential part of modern life, powering everything from personal devices to industrial systems. Traditional wireless communication technologies primarily rely on radio frequency (RF) transmission, which faces challenges such as bandwidth limitations, interference, and restrictions in sensitive environments like hospitals and aircraft. This paper presents a prototype system for image transmission using Light Fidelity (Li-Fi), a wireless communication technology that utilizes visible light. We propose a method in which grayscale images are converted into binary data via Python, and transmitted using LED pulses controlled by an Arduino. The receiving end employs a photodiode and a comparator to detect signals, which are then decoded and reconstructed by a Raspberry Pi. The system transmits images at a fixed bit rate of 4 bps using a simple protocol with periodic start sequences. Our results demonstrate successful image reconstruction but also highlight challenges such as synchronization drift and limited throughput. This work showcases the feasibility of Li-Fi-based image communication in low-speed, RF-sensitive applications and provides a basis for future enhancement.
