VLC (Li-Fi) - Communication and Coding

Hi everyone,

I am currently working on a VLC (Li-Fi) project and the main goal is to send information from a computer (server) to another one (client) but that information must be coded with the Huffman algorithm.

Right now I have set up a system similar to the one developed by Robbert Hofman (http://robberthofman.me/projects/2016/03/29/visible-light-communication/) in which the information is sent character by character but I am not clear how can I send more information and that this is codified.
Also I have been working on the program in C++ for the Huffman coding.

Sorry I didn't detail more information before. I would really appreciate your help! :slight_smile:

What have you done so far?
