    I remember Harald Haas show this on a TED talk over 10 years ago. Strange that, despite its many benefits over WiFi, we still don't have this implemented everywhere.

    Thank you for your explanation...I was trying to make this for my school project but I can't find any proper explanation videos on internet...I got a nice clarity from your video❤...

    This is the only channel by far that discussed protocol. The best video on TH-cam.
    Just one doubt, how can we speed up the speed of transmission? by making an efficient protocol? If yes then how to build this? Cause I was thinking to make a project on transferring internet using this tech. Please help me.

    Really nicely done Charlie! Very cool as always

    Can you explain this vid without the neopixel jewel instead using led and can you explain the code for the faster output

    Great material and delivery, keep it up!

    A really nice video. I hope if you can use LEDs as transmitter and receiver. Good luck Charlie.

    Hello, the preamble you mentioned, where should it be, on the transmitter or receiver

    please I am trying to redo this experiment using a standard led instead of neopixel jewel. I do not know what changes to make to the code so it should work. anyone please help

    Could you explain how can we send video also using this technology

      Very Very slowly
      Hello, World! - is 12 bytes and it takes approximately 1 second using that method
      if you were to say send a GIF, the average GIF is about 20kb (20,000 bytes)
      to send 20,000 bytes this way would take around 1666 seconds (27 mins)
      to send a video for example - a 5 minute video at 1080p would be about 170MB (170,000,000 Bytes)
      this would equate to 14166666 seconds or aprox 164 days at that speed
      so, whilst with this setup technically possible, it would be highly impractical
      But... if you wanted to do this, you could convert a video into binary send that over and reverse the process the other side

    madam arduino have its own cod programm ,but here how java script is interfaced

    How about sending videos?
