Bidirectional visitor counter

i wan to build a project on bi directional visitor counter using IR led, micro controller 8051 and seven segment. can anyone provide me a tested and working circuit diagram plz

No I can't but.

There must be many 8051/8052 clock and 7-segment projects on the internet.
Remove the 1 second clock and add (on input advance the counter)
The clock program counts up (+1) so adding a count down (-1) should not be hard.
The clock has divide by 60 counters. You should be be able to change to divide by 100.

You can learn much form a similar project.

I put some examples of the same in the articles section... in both ASM and C

HI . I SEND U bi directional visitor counter ASM CODE HEX WITH PROTUSE FILE . ITS 100% WORKS.

Thank you, It is good to hear you have it working. Also good that you posted the code so others can learn.
