In the visible light communication in which data is superimposed on light, the communication range is visible. In pulse position modulation, for instance, when one image utilizes four openings, quad data can be sent by turning on just a single space among the four openings and killing the other three openings. In this strategy, the brightness becoming ¼ and feels not flicker but rather darker than when it is always on. Then again, when-when inverted pulse position modulation in which these openings of ON and OFF are switched is utilized, since one space is OFF, and three openings are ON, the brightness becomes 3/4, which does not turn out to be too dark. In this paper, we analyzed a crossbreed adjustment that can change the brilliance other than 1/4(25%) or 3/4(75%) by joining these pulse position modulation and reversed heartbeat position modulation. Visible Light Communication (VLC) utilizing light discharging diodes (LEDs) is an innovation that gives a chance to rapid minimal effort remote correspondence, being an option for successful and effective correspondence that can adapt to the real fast remote administrations request. This paper focuses around darkening mechanism that can be implemented in VLC frameworks to save energy and give exact illumination control. The inspiration behind this control mechanism, decrease and flow difficulties in down to earth usage, driver hardware, ongoing advancement, and future prospects are additionally concisely introduced.
