Abstract :

The application of Visible Light Communication (VLC) for transmitting text and audio data. The system utilizes readily available components for a low cost and practical implementation. For the Text transmission, an Arduino microcontroller processes the text data and modulates the intensity of a mobile phone torch light (LED) based on the information. The modulated light signal is captured by a Light Dependent Resistor (LDR) sensor. Another Arduino detects the variations in light intensity and decodes the transmitted text, displaying it on an LCD module. Similarly for the Audio transmission, the audio signals from a mobile phone’s audio jack are fed into an LED. The varying audio voltage modulates the light intensity of the LED. The light signal is converted back into electrical current by a solar panel. An audio amplifier boosts the weak current to a level suitable for driving a speaker, reproducing the transmitted audio.
