Wireless Communication Using Visible Light Spectrum

The number of gadgets accessing the internet is increasing every day in a world of wireless technologies. The majority of devices use wireless connection to access the internet and share data, which has unfortunately increased network complexity and increased the risk of radio frequency interference. This has resulted in a significant decrease in available spectrum for future devices. We should seek out an alternative medium that provides both high bandwidth and security. We should seek out an alternative medium that provides both high bandwidth and security. In terms of transmission speed, security, and usability, the visible spectrum represents a completely new paradigm in wireless technology, comes to mind when we think about such criteria. This project describes and implements a transmission system for audio and data using the visible spectrum as medium I.e., By fast and precise variations in the light intensity by a controlled current of the LED, data is transmitted from transmitter to receiver using visible light as a medium and a photo diode senses the variations at the receiver end which is controlled using ARM microcontroller.
