This is an USB Physical Hit Counter.This version requires one MCU to communicate between PC and 7-segments display driver.I decided using AVR and this is my first AVR project.The purpose of this project still same as previous version.Therefore,it used to count and display the total page hits on any website instead of using only general scripts such as PHP,Java,CGI etc.The host software no USB driver programming required.

This is a physical hit counter.It used to count page-hits on the website instead of using software only.The counter will be connected to rs232 port through a few of electronic components that performs as a counter driver and power supply circuit.The counter that I used is a mechanical counter or electromagnetic counter model SC-212 which I get from an old coin-op game machine as show in the photo.As the counter’s nameplate specified, this counter requires 12VDC power supply, this means that it requires a 12V pulse to increase the counter by 1.Also,the in the nameplate show the maximum speed is 15 CPS, but I not use beyond this speed in my project.
