Abstract

Optical communication is a type of light communication in the range of the electromagnetic spectrum, which is Infrared, Visible Light, and Ultra Violet light that used to transmit signals in the transmission system. This system operates in the visible band referred to visible light communication. Visible light communication is suggested to overcome the problem of radio frequency spectrum as it has more advantages. Visible Light communication uses light pulse to transmit data instead of radio wave. White LED is used as the light source for both illumination and communication purpose. Visible light communication has a secured data transmission channel as light cannot penetrate wall. The designed transmitter and receiver of the system is tested in simulation using the software OptiSystem for the optical part and software Proteus 8 for the electrical part, thus further developed into a prototype. The simulation in OptiSystem is done with different length of FSO Channels and different number of LED settings. The simulation in Proteus 8 is done for transmitter unit and receiver unit. The optical and electrical part is used Arduino Uno to obtain the final prototype. The result gained from the project will be analyse and compared in different distance between of LED to LDR, power received of LDR, and brightness of LED.
