Thank you. As a note, you can find similar projects too. The idea doesn't belong to me. ;)

Well i did and that helped too, but thanks for posting as i didnt know about it. i made one yesterday with 3 meters, no leds yet. what software are u using on the pc to send to the arduino  ? i spent a while trying a few options, and ended up finding a fork of Open Hardware Monitor with serial support, which is great as it has many stats to choose from. https://github.com/cody82/open-hardware-monitor

here's my project page : https://hackaday.io/project/10629-pc-analog-panel-meters-w-arduino

I checked your project, it looks cool. I did a little modification on the software found on http://www.lungstruck.com/projects/pc-meter/ (you reffered to this page too) basically for changed serial protocol. I will look at your forked code.

Hello Alper, If it's not too much of a hassle, I'd like to see the serial protocol modified version of the lungstruck.com PC meter software as I am trying to work out a port of the code for use on linux systems.

Hi,

Do you want to use aPCmeter with the modified software or just want to see the modified version without using it aPCmeter? Later, I didn't use the modified software this was only for initial tests. Although I didn't publish it yet, I wrote a Python script from scratch to communicate with aPCmeter properly. If you wish, I can send the Python script run on a computer to use aPCmeter. The my modified version of the lungstruck.com may not help you much depending on your needs because as far as I remember, I changed couple of lines.

cool idea !
