AUDIO TRANSMISSION VIA VLC Engr. Arlene C. Grate Marc Anthony B. Gonzales Renz Mark C. Rico

----------------------------------------------------------------------------------Abstract- Visible light communications is the emerging technology nowadays. Using visible light to transmit information to the receiver is the basic principle of this technology. Integrating communication to visible light is the main concern of this study. In this paper, the researchers presented a wireless audio transmission using visible light. The system consists of audio source (from microphone or portable devices), transmitter circuit (where the visible light is connected), and a receiver circuit (an audio amplifier with solar cell attached to it).The researchers aim to provide a two-way wireless communication using visible light. Keywords: Visible Light Communication, Wireless Audio Transmission -------------------------------------------------------------------------------------------

Introduction You will not lose your eyesight by looking at the bright side of life (Arlega, Evelyn. 2012). Looking at the bright side of visible light will lead you to the most advanced way of communication, without being hurt of course. Technologies are not made to hurt humankind but to help them live their lives to fullest.

Visible light is only a small portion of the electromagnetic spectrum that fall within the visible range of humans (0.3PHz to 3PHz). Due to the electromagnetic spectrum congestion nowadays, researchers from different parts of the world found a new way of wireless optical communication by utilizing the visible light. Communication using visible light is not harmful to humans because they can perceive it and can act to protect their eyes. It is also not harmful when used in environments that 1
