Abstract

Visible Light Communication is seen as a promising option for 5G communication because to its characteristics such as operating in a non-licensed frequency spectrum, offering high bandwidth, using minimal power, and being immune to electromagnetic interference. This property allows light waves to transmit data faster and convey more information, making VLC a promising solution for providing universal electronic navigation assistance to visually challenged individuals. VLC utilizes the visible light spectrum (450nm-750nm), offering a greater bandwidth for data transmission. Light Emitting Diodes (LEDs), commonly used for illumination, have become efficient communication sources in VLC systems. VLC may serve as a means for transmitting data or providing light. This article presents a demonstration of a transmitter and receiver circuit based on Arduino for the establishment of Visible Light Communication (VLC) localization. LEDs are used for the purpose of transmitting a distinct level of brightness, while a phototransistor is utilized to receive the light signal and transform it back into an electrical signal. The item and positions of an unknown target are identified based on the received signal strength. The prototype we present accurately determines the precise position of the receiver and minimizes errors in object localization.
