Understanding Hello You

System Overview

We can look at a visual explanation of how the system is working in the diagram below.

helloYouSketch.ino (The Arduino code)

The Arduino code written in C++. It may be written or edited on the IxE itself, but it is compiled, uploaded and run on the Arduino board.

server.js (The RPi code)

The server.js code is written in javascript. It is run on the IxE using node.js.

index.html and client.js (The browser code)

Index.html is written in html, but with javascript embedded. The client.js code acts as a library for the functions called in index.html, and is written in javascript. These files are served from the IxE when node.js is running server.js. Both run on the web browser.
