Abstract

In recent years, visible light communication is attracting growing interest for wireless communications since it is low-cost and easily maintained by using high-speed switchable LEDs. We have developed a prototype to demonstrate wireless visible light communications using RGB LEDs as both transmitter and light source. The RGB LEDs enable parallel signal communications, and a PSoC microcontroller is used to control them, thus significantly reducing the need for extra circuits and allowing rapid modification of communication software. A prototype system was developed and its validity was confirmed.
