| Abstract | This research describes a design technique to control brightness of LED(Light Emitting Diode) light bulb that can be able to mix communication signal into visible light. This method is called Visual or Visible Light Communication (VLC) by put frequency in visible light and receives response back from receiver by Infrared. This method can be used for many various applications. In this research will test 3 applications, 1st Display message on LCD display via VLC for Electronics price tag, 2nd Application for Electronics Voting System and 3rd Application for temperature monitoring. Other feature is identically control brightness each LED light bulb for utility usage. |
