Light Fidelity-based Home Automation System with Arduino

Arduino based home automation system is envisage in this work using the principle of light fidelity. Light Fidelity (Li-Fi) is the fastest means of wireless communication which uses visible light to transmit data/signals between devices and is one such concept that is gaining momentum to become the possible alternative solution for overcoming the crowded radio spectrum for wireless communication system. In this paper a simple prototype of arduino Li-Fi based transmitter and receiver was designed and implemented. The Arduino transmitter processes and sends out visible light signal emitted from white LED bulb when a functional pushbutton is pressed and the arduino receiver receives and process the signal and acts to switch ON or OFF the connected household appliances. The system was made using readily available materials and the transmitter and receiver can communicate up to a maximum distance of 41cm.
