Abstract
With the development of technology, the constraints and the needs in the field of communication have increased. Especially, limited and licensed radio frequencies that can cause electromagnetic interference and health problems in the use of wireless communication make the visible light communication (VLC) technologies very important. In this study, an ARM based VLC system design has been realized to implement a unique product with the use of low-cost and commercial off-the-shelf electronic components. In this context, receiver and transmitter circuits are designed, printed circuit boards and appropriate enclosures have been produced, as a result, a system prototype has been created to use in interior applications with standard ceiling height. The design is also one of the few implementations in which orthogonal frequency division multiplexing (OFDM) modulation and digital signal processing applications are performed by using ARM based microcontroller. Consequently, the system communication is achieved at a data rate of 3.5 kbps from a distance 1.8 m to 3 m. Also the system communication is successfully performed from the center of the light source up to 85 cm distance on the direct side and up to an angle of 50° on the azimuth.
