   A nice project from justDIY Project Log, as the author is saying he created this project one day when he was boring and needed something “to ease his racing brain …” not many people can create something this nice when they are bored. Led projects like this are always fun to build and to watch them working. I recommend this project to everyone who has a bit of experience with microcontrollers. You can get full info, schematics and source code for this project from here Link
