The Project Workspace
When the user first loads the web interface they will see the current image of the the LCD Display.
They enter their name (if omitted Anonymous is used), and the two lines of text for the LCD Display. If either line is less than 16 characters spaces will be added to the end of the line to make it 16 characters.
Clicking the "Change The LCD" button will call the Java Servlet. The Java Servlet takes the text from the form and writes it to a file. The servlet then calls the "display" C program which reads it's input from the input file.
There will be a short delay to wait for the data to written to the display and for the webcam picture to be taken.
