Modifying Emitter and Receiver

[tsaferrari]

Hi jpiat! Thanks for the demo on VLC using arduino! I am trying to implement VLC using high power LEDs which are normally used for lighting instead of the regular ones. Unfortunately, the drivers for these LEDs are fixed and are not programmable. Could you guide me how I can replace the emitter with these high power LEDs as I see that you have also used a similar emitter? Did you used MOSFETs to drive the high power LED? P.S : As a receiver I will be using my camera phone to detect the light and hence the need for high powered LED. Any help will be greatly appreciated! Thanks
