AUDIO AND TEXT TRANSMISSION USING LI-FI TECHNOLOGY

Abstract

The project "Audio and Text Transmission Using Li-Fi Technology" explores the innovative application of Li-Fi (Light Fidelity) for transmitting both audio and text data. Li-Fi employs light signals, typically from LEDs or lasers, for data transmission, and in this project, it is leveraged to achieve two distinct functionalities: audio and text transmission. For audio transmission, a dedicated Li-Fi system is implemented where an audio signal is modulated onto the light signal emitted by an LED or laser. At the receiver end, multiple amplifiers are employed to retrieve and reproduce the audio signal. This process allows for the wireless transmission of audio data using light waves, offering a unique and potentially efficient alternative to traditional audio communication methods. For text transmission, Li-Fi modules connected to Arduino boards are employed for both the transmitter and receiver. The Arduino-based system facilitates the encoding and decoding of text data into light signals, enabling the wireless transmission of textual information using Li-Fi technology. This dual-functional approach expands the versatility of Li-Fi in communication systems, showcasing its potential for transmitting both audio and text data wirelessly through light Keywords: Arduino, Li Fi Transmitter, Li Fi receiver, LCD
