We all are using some sort of visitor tracking system for our websites. But all of them are online. But wouldnt it be cool, if we had a physical visitor counter, almost like the odometer of a car, which showed the visitor count in realtime. This is a simple project, but requires skills in electronics and some web programming also. The LED part can be settled by using seven segment displays.

Ready made circuits are available in which the counter is automatically increased when a pulse is given. The circuit can be connected to an SBC running linux. The SBC will host a program that will listen to a port on the server where the script is hosted. The port is updated whenever a new visitor comes and thus the LED display is also updated.
