locked. A low Y3 line indicates that both signals have been blocked. Refer truth table of the IC 74155. The four output lines act as control and decoding signals for the remaining circuits.
The sequence detection logic circuit consists of three flip-flops for detecting the incoming as well as the outgoing vehicles. The Y0 line is connected to the clear lines of all the flip-flops, which gives zero at their respective outputs. The vehicle entering the parking area must interrupt the first sensor (before entrance), then both the sensors and finally just t..................[:=> Show Contents <=:]

The counter is set based on the seat of theater using a button. And one person entered the counter get decremented .when all the seats are occupied by viewers the counting system stop. and it indicate ‘HOUSEFULL’ by using a LED and the door is closed permanently. So no one can enter the theater until the show is finished.
The main advantage of this project is to reduce the rush of people in theater no malpractice held. It also can use in high secured function and other meetings.

This Telephone Operated Calling circuit is used where persons have to be called or signaled. When you need to call a person amongst many standing outside a cabin, just lift the telephone handset off the cradle and press the respective number. The number of the person called will be displayed and a bell will sound to inform the person that it is his turn. This circuit is very useful for doctors for calling patients, in banks and in various other situations.
