This is a page listing a few dabbles with the Ardunio and Colorduino. I have used SVG to simulate an 8x8 colour display and JavaScript to animate it.
I decided to order a Colorduino. Before it arrived I used an SVG image in a web page, and JavaScript to set the "LED" colours.
I used SVG-edit to setup an 8x8 matrix and JavaScript to animate the display.

I ported some Colorduino examples I found on the interenet:
Colorduino_Schematic_and_Demo_Code_demo - just the graphics and fonts tables. Colorduino-master Colorduino-v124 colorduino i2c demo
http://wiki.iteadstudio.com/Colorduino http://wiki.iteadstudio.com/Colorduino_V1.3
Here are some SVG graphics with animations using javascript:-

Colorduino_Schematic_and_Demo_Code_demo needed some work to build it. I added:
/* comment out Pins_Arduino_h by defining Pins_Arduino_h as it was giving a compile error*/
#define Pins_Arduino_h
/* http://katalytischerkonverter.com/2014/10/04/colorduino-tutorial/ http://www.instructables.com/id/Lampduino-an-8x8-RGB-Floor-Lamp/step16/Programming-the-Colorduino/
Another way is to use the embedded FTDI chip in an Arduino Duemilanove. Simply pop out the ATmega MCU from the Duemilanove board, and make the following connections between the two boards:
I used the UNO and set the BOARD type to Arduino Duemilanove in the IDE.
Arduino RX -> Colorduino RX Arduino TX -> Colorduino TX Arduino Reset -> Colorduino DTR Arduino 5V -> Colorduino VDD Arduino GND -> Colorduino GND
Then, you can connect your Arduino to your PC via USB, and select Arduino Duemilanove or Nano with ATmega328 from the Tools->Board menu of the Arduino IDE.
remove uno chip and use
1 - RESET 2 - RXD 3 - TXD 7 - VCC 8 - GND
/* comment out Pins_Arduino_h by defining Pins_Arduino_h as it was giving a compile error.*/
#define Pins_Arduino_h

Quite often a way to plt graphs would be useful.
You have a C program or PIC chip that outputs results.
The Arduino IDE has a serial to Graph plotter in it.
Excel can be used, but does not cope well with output.csv being updated.
A web page that runs off the desk top and auto reloads makes a useful tool.
First use with updates:- http://www.dougrice.plus.com/rt004/sr3/reportSVG.svg
C Program outputs to f.js.
Webpage reload f.js and replot every few seconds.
