The Visible Light Communication (VLC) is leading technology, with benefits of secure data communication, high energy efficiency, high data rate, long life and safe wireless communication. Moreover, it depends on fast switching of LEDs and the modulation of the lights waves. In this paper we offer an easy to execute and low cost VLC-based indoor system. The system is formed by LEDs which behave as a transmitter and a receiver interface connected to a mobile via Bluetooth, where a visual application runs. Moreover, LEDs are used not only for communication but also for lighting of indoor environment. Our approach reveals its advantages as globally consistent, low-cost, easy installation and it retains the potential applications using Visible Light Communication. This paper emphasizes on dimming and data transmission feature of VLC for indoor environment.
