December 3rd, 1990: The earliest known HTML document: http://www.w3.org/2012/08/history-of-the-web/origins.htm
<h1>Standardisation</h1>
There was not a lot of discussion of this at <a href=Introduction.html>ECHT90</a>, but there seem to be two leads:
<ol>
<li><a href=People.html#newcombe>Steve newcombe's</a> and Goldfarber's "Hytime" committee
looking into SGML, and
<li>An ISO working group known as MHEG, "Multimedia/HyperText Expert Group".
led by one Francis Kretz (Thompsa SA? Rennes?).

/*
* rgb values are sent to the arduino board and as a comma seperated list of decimal codes of 0-255
* for example rgb could look like this 213,89,46.
* This program accepts these codes form serial comm port and seperates rgb values using (,) comma as the seperator
