New post for Arduino 0017 here –> http://transitlab.org/2009/arduino-and-the-eeepc-ii

I recently bought an asus eeepc subnotebooks( 4G ssd, 512ram, portable celeron) for a portable blogging computer. I never expected to install processing.org or arduino even though I use them on another computer. However, the people down at the eeepc wiki have posted a method of installing both(here) . I have installed arduino and processing(instructions ) on it. So now I have an ultraportable kit to play with arduino and processing! >> 2kg! Its not a fast system for processing, but adequate for trying out patchs, and fine for communicating with arduino.

Cool.

Now I am working with the kingbright chameleon rgb led modules(available at Maplin and Rapid ), getting arduino to handle the physical interface of controlling the 3 leds(on/off done) and processing.org the mix of colors from an onscreen interface(in the process).

To do this I have used the example code from fading and blink, and merged the different ideas.

I hae also been getting to know led modules, their orientation, the value of the resister needed for each. (ie the Blue operates at a higher voltage than the Red led, needing different resister values).

This is primarily because LEDs do not provide a resistance to current, if the voltage is above the operating voltage of the led, then the led will suck more and more current until it burns out. Thats the reason to put in the resister, it controls the current (usually 20milliamps up to a max of 50milliamps)(some links can be found at http://del.icio.us/sctv search for led.

Will post the code as it gets more mature, for now I am verry happy to have this nice little development package for arduino and processing.
