Li-Fi (Light Fidelity) technology is a cutting-edge kind of wireless connection that transmits data using light waves rather than conventional radio frequencies. It investigates the use of Arduino, a widely available and reasonably priced microcontroller platform, for Li-Fi data transfer. A straightforward and effective Li-Fi communication system that is simple to incorporate into a variety of applications is proposed in this research. The system is made up of an Arduino board interfaced with a light-emitting diode (LED) for data transmission and a photodiode for data receiving. In order to facilitate smooth data sharing between devices in a Li-Fi network, a communication protocol must be developed. Unlike the conventional Wireless Fidelity (Wi-Fi) architecture, Light Fidelity (Li-Fi) technology is a wireless communication system that uses the visible light spectrum to deliver data quickly and securely. This paper describes a Li-Fi communication system that makes use of a smart phone. By using the built-in smart phone flashlight as a source to send data and detecting the impact of employing external light detector sensors attached to an Arduino UNO circuit to receive data, this suggested method seeks to maximize the bit rate with high precision. In order to determine which light sensor could achieve a greater data bit rate and to test the system's performance under varying transmitter-receiver distances, four practical experiments were carried out. The evaluation findings showed that the suggested research outperformed the others in terms of data bit rate, reaching over 100 bps with 100% correctness.
