hello , i have a digital home work , its about an elevator control , the home work is ,
we have a first and a second floor and we have 2 inputs up and down , also if we were in the first floor , the door will open for some time and then close , and if we were in the second floor , the door will open for some time and then close , so we have 2 inputs ( up and down ) and we have 3 outputs ( first floor , second floor , door ) , the door is 1 when the door is open .
i have tried solving it , and i get this ,
i make 6 states ; the first , the second , the second is open , the second is close , the first open , the first closed ,
i also make the state table and digram
but there is a problem , i couldnt find a way to make the door open for some time and then closed , we have to use 74LS93 counter , but i dont know how to use it here ,
thank you
