Computer Monitor Using Arduino and Node JS

This instructables will show how to monitor your computer hardware while doing another things on your computer. I always had problem to check my hardware while playing games, programming and etc… that is why I decided to make this Computer Monitor using Arduino; I called it Retrovisor (Rearview mirror in portuguese). Using this you can check your CPU / memory usage, process running, stand by process, battery life and network usage without opening any screen on your computer. For this I used an old font case, arduino Duemilanove, 4x20 LCD and node.JS.”
