The project proposes a novel method of data communication using Li-Fi technology. The proposed system utilizes the Android mobile phone's flashlight to transmit data in Morse code, which is then received by an Arduino Uno board using an LDR sensor. The received data is then displayed on an LCD screen, and also sent as an SMS notification using a GSM module. The proposed system offers an alternative to traditional communication methods that rely on radio waves, such as Wi-Fi and Bluetooth. The system is cost-effective, secure, and offers a high-speed data transmission rate. The Arduino Uno board uses an LDR sensor to receive the modulated light signal and decode the Morse code. The received data is then displayed on an LCD screen, which can be used to display messages or other relevant information. Additionally, the system can also send an SMS notification using a GSM module, which can be useful for sending alerts or notifications to the user.
