Abstract: Digital Visitor Counter is device or system that can read the incoming and outgoing agents or traffics that tends to visit or physically visit a place and. The system is proposed and designed in this paper that is the visitor counter that is bidirectional in feature which can read both the incoming and outgoing traffic and agents at same time securely. In this system, up to 999 incoming or outgoing visitors can be counted using microcontroller. Microcontroller is used here to make a secure count over a large number of visitors. This system is essentially required in many places where count for the visitors is needed by the administrator of that system. The design and demonstrations are produced in this paper.
