Abstract
The full-duplex star redundant system of visible light communication (VLC) for indoor utilization was developed by adding an IR transmitter into the slave part and an IR receiver into the master part of the previous system, which had only an LED as the transmitter and a photodiode as the receiver. This development allows the system to be capable to transmit and receive images and audios in addition to mere texts as before. The transmitted data were encoded with the technique of Manchester encoding, and then tested with 3 types of photodiodes namely VBPW24R, FDS10X10, and OSD100-E. The data transmission was backed up with 3 LED modules that were controlled by an Arduino microcontroller in case one of the modules is damaged. Moreover, the system has functionality in notifying users via the status monitor to check when malfunction happens with any module.
