The Li-Fi Data Transmission System is an optical wireless communication project that transmits data using light instead of traditional radio frequency signals. The system uses a laser diode as the transmitter and an LDR (Light Dependent Resistor) as the receiver.
Text messages are encoded using Morse code and transmitted as light pulses, which are detected by the receiver and decoded back into readable data.
To demonstrate wireless data transmission using visible light communication and implement a basic Li-Fi communication system using low-cost components.
