The aim of the project was to design a prototype of 'Light Fidelity' System that would be used in visible light communication application. Apparently the light fidelity system would contain an intelligent programmable light source and receiver to decode the message.The intelligent programmable light source was a LED Light source that can blink at 1000’s of times per second.This blinking pattern corresponds to actual data being transmitted.This high speed flicker cannot be seen by our eyes; however an ordinary unmodified mobile camera sensor can see these changes. There is app on the mobile that decodes this data to show meaningful information. We have also try to implement this technique using LED and Arduino UNO Board.LED is programmed via Arduino UNO Board and it encode the message in pattern of 1s or 0s (on or off) which can be decode by mobile app. The receiver camera should have the roller shutter.
