Abstract

Electronics Engineering
Arduino UNO, Arduino NANO, LED (Light Emitting Diode), 16*2LCD (Liquid Crystal Display), Solar Cell.
Li-Fi (Light Fidelity) is an emerging wireless communication technology that uses visible light to transmit data, offering a promising alternative to traditional RF-based systems like Wi-Fi. This project demonstrates a simple Li-Fi data transfer system using an Arduino microcontroller. The system utilizes Light Emitting Diodes (LEDs) as transmitters and Light Dependent Resistors (LDRs) as receivers to transmit and receive data through light intensity modulation. In the transmitter section, an Arduino is programmed to encode binary data and control the switching of an LED. This LED rapidly blinks ON and OFF to represent binary '1's and '0's, effectively converting digital data into optical signals. On the receiver side, another Arduino reads input from an LDR sensor, which detects changes in light intensity. These changes are then decoded back into the original data. The received information can be displayed on a serial monitor or an LCD module. The system is designed to transfer simple text data or binary messages over short distances in a line-of-sight environment. It is low-cost and easy to implement, making it suitable for educational and experimental purposes. While this prototype is basic, it showcases the core principle of Li-Fi: data communication via light. It highlights the potential of Li-Fi in areas where radio frequencies are restricted or cause interference, such as in hospitals, airplanes, or underwater communication. However, it also reveals some limitations like sensitivity to ambient light and limited range, which can be addressed in future advancements using photodiodes and optical lenses for improved efficiency and speed.
