Heya guys. Im planning out my project for later this year and i wanted to an LED display which would indicate how much the individual cores on my cpu are being used. I was looking at doing 2 columns of 10 LED's. first 4 would be green next 3 yellow and the remaining 3 red. I would like it to be near enough real time or updated every 3-5 seconds. I dont know how about going to do this and was wondering if its been done before, if it has or even if it hasnt do you know of any links that would help me out with achieving what i desire.
