i am trying to design an up down counter circuit which will increment counter when a person enters and decrement when a person leaves a room.
but the problem is,how will i pass 1/0 when a person enters/leaves a room to up/down the counter?
i want to add some more things.
it will be a mod-60 up down counter
there is only one door for entrance and leaving
assuming that no person will try to trick the counter
i have already designed the counter circuit and seven segment display
how to pass 1/0 to the counter?
i have tried to do but at the end of process everything is wrong
i am totally confused.
need a block diagram badly.
thanks is advance.
