Sequential Design Example: Elevator

[@TechOne7671]

It’s 30 years since I did combinational logic at college, it would have been better if you were my lecturer. Cheers for the memories.

Hey man, your video helped me with my exam, thank you

[@TheBritobr]

Thank u from Brazil!!!

[@attchrisgomez]

Thanks for this awesome video, it was very helpful!

[@chrishadjipetris6059]

Then if want to have 4 pushbuttons, one for each floor, you can add priority encoder 4 to 2, in order to add a keypad with keys 0 to 3. I implemented this state machine on FPGA, by turning a similar design to this into a block, I used the encoder I had from another exercise and I used 4 pushbuttons as inputs. I also used the 7 segment display to display the current floor

[@ZainabHubail-cz7ho]

Nice, can you share with me your design?

[@tsfrejeymx5035]

hi sir,how i can contact you to know more abt ur design??

[@rasha2586]

But in the video it’s only two pushbuttons right?

[@eliya5395]

Thank you, this is the best explanation!

[@alialjabirable]

Thank you very much, this really helpful

[@cianmoriarty7345]

A disturbing number of people seem to be coming to this video to make actual controllers for real elevators 💀🤯

[@taqikhan5418]

Thanks For the nice explanation sir😊😍

[@motezart2867]

Wish these existed when I took the class

[@kartikhegde533]

You look like Alec Baldwin. Between very good explanation.

[@marthabeatriz1161]

Love it!!

[@praneshr4592]

Sir, What if the elevator has 7 floors and have a certain sequential order like 6 5 4 2 6..... ?

[@DowntotheWires]

I hope you were able to complete your homework assignment without me :)

[@ZainabHubail-cz7ho]

Good explanation. I have question. What will be your modification if we want to make sure that the elevator never accept any input until it reaches its destination. For example, if the current floor is G, I request floor = 3. The elevator keep moving until it reaches floor =3 even if there is another person request the elevator for other floor. Thanks

[@tsfrejeymx5035]

Hai skrg awk kena buat projek utk elevator control ke??boleh tak sya nak tgk circuit?

[@rasha2586]

Is this only two push buttons? One for down and one for up?

[@jushuaramos7419]

How can we add a system where there is 0-4 number keypad in order to link in the elevator destination?

[@kshubham1]

What about the opening gate after reaching the floor, if we take it as output then how it will work in this state diagram, as per my understanding you have drawn a melay machine state table if we consider output also in state table, correct me if I'm wrong. Please reply to me sir.

[@DavidGerhardDR]

in this case the output would be the same as the current state (if the elevator is at floor 3, open the door at floor 3) so the design would be unchanged

[@mohamedabukrawi2094]

It's amazing lesson

[@vikashr.dharmaratne3330]

Thank you

[@sahilgupta2210]

Can this system be called an FSM (finite state machine) if I m not wrong?

[@DowntotheWires]

Yes! a finite state machine consists of a set of states (the floors) and a set of transitions between the states.

[@eliya5395]

@@DowntotheWires So since the output IS the state, it's a Moore FSM?

[@DowntotheWires]

@@eliya5395 That's correct!

[@vinayakakarthik4259]

Is this Moore or meally

[@yonaszelalem9870]

what if the there were 5 floors?

[@AmdadulHaque-f3s]

you have to use 3 bits then
