i have been given the project of uni-directional counter.......using logic gates................
i have google it and found that all the circuit given there are bi-directional...... using ir sensor , 555 ic and decode counter for 70-segment...
what i need is to make a circuit which only counts when someone gets it.... it should give "1" output when someone comes out of room....
i have to make this using logic gates.... what comes in my mind is to use two ir sensors so one works if it gets output first............or something like that.......
share your suggestions....
