Resumen


Resumen

La comunicación por luz visual o VLC por su acrónimo en inglés (Visual Light Communication), emplea la luz visible proveniente de lámparas fluorescentes, o bien luz de diodos emisores de luz (LED: Light Emitting Diode) para transmitir información. La transmisión de la información se realiza modulando la intensidad de la luz del LED. En el receptor la información es inicialmente recobrada a través de un foto-detector, que suele estar conectado a un dispositivo para la recuperación final de la información. En este artículo se describe una aplicación basada en VLC, para transmitir audio almacenado en una tarjeta micro SD empleando un shield montado sobre un microcontrolador Arduino, y varios módulos (llamados bits) de LittleBits. El emplear componentes modulares que permiten de manera simple su interconexión, facilitó el desarrollo de esta aplicación.

TRANSMISSION-RECEPTION OF AUDIO VIA VISIBLE LIGHT

Abstract

Communication by visual light or VLC by its acronym in English (Visual Light Communication), uses visible light from fluorescent lamps, or light from light emitting diode (LED) to transmit information. The transmission of information is done by modulating the intensity of the LED light. In the receiver the information is initially recovered through a photo-detector, which is usually connected to a device for the final recovering of the information. This paper describes an application based on VLC, to transmit audio stored in a micro SD card using a shield mounted on an Arduino microcontroller, and several modules (called bits) of LittleBits. The use of modular components that allow simple interconnection, facilitated the development of this application.

Keywords: Arduino, Audio, LittleBits, SD shield, VLC.
