Abstract:
The design and implementation of a data transmission system utilizing Light Fidelity (Li-Fi) technology are presented in this work. Li-Fi transmits data quickly and securely using the visible light spectrum, making it a promising alternative to traditional wireless technologies like Wi-Fi. The system comprises two circuits, with an Arduino Nano as the receiving circuit and an Arduino Uno as the transmitting circuit, programmed using C++ language on the Arduino IDE. The received data is displayed on the receiving end. The paper also discusses the applications, features, and comparison of Li-Fi with Wi-Fi. While Wi-Fi is suitable for general wireless coverage, Li-Fi excels in high-density wireless data coverage in confined areas and where radio interference is a concern, making them complementary technologies. Li-Fi offers better bandwidth, efficiency, connectivity, and security than Wi-Fi has been tested at rates more than 1 Gbps. The low-cost nature of LEDs and lighting units presents numerous opportunities for exploiting this medium. Li-Fi uses light to transfer data by bypassing fibre optics and transmitting data through LED light bulbs. Overall, this paper demonstrates the practical application of Li-Fi technology using the Arduino programming platform.
