Demonstration of visible light text data transmission system using LED lamp

This paper proposes a study of the visible light communication system. These systems are the novel A technology that can modulate the TEXT data along with the light sources and send the modulated signal form the transmitter to the receiver by using the light with a frequency range of 400 - 800nm. The aim of this paper is to transmit the serial TEXT data pass through the 5W LED lamp illuminating to a photodiode of the receiver. The received signal was amplified and transmitted to the computer. The results of the proposed method are shown the baud rate of data transmitted by the system was 115200 and the maximum of the distance between the transmitter and receiver was 5.4 meters.
