LED brightness based on CPU temp

Hello everyone.

So I had an idea.

I am making an acrylic case, and I was debating between using red or blue lighting.

Then I thought, what if the light would change color from blue to red? What would be a good paramater to use to vary the color? how about CPU temp!

So, does anyone have the slightest clue how one would go about this? I would think an arduino would be able to handle this quite easily, but would an arduino be overkill?

For example, at 30C core temp, the red light is at 0 pwm, and the blue light is at 255 pwm (full brightness). at 75c, the red light is at 255 pwm and the blue is at 0, and vary the pwm signal to the 2 led's based on core temp.

Thanks for any suggestions.
 
Interesting idea. The most straight forward way (as straight forward as something like this could be) is by using external hardware. A really basic PLC would work. Pun intended: something like a Basic STAMP microcontroller. Then add your temperature probe and write a simple PBasic or C++ program to set your temperature : light parameters. In all honestly, probably not worth it unless you came up with a way to use the PC to control it. But I'm not savvy enough on that to offer any advise.
