could you help me on our project we need to create a 4 floor elevator circuits and program may help us ! thank you

 

Is this a school project?

 

There is a thread here
http://forum.allaboutcircuits.com/threads/how-do-you-implement-a-state-machine-in-a-micro.121147/
that discusses state machines for elevator control. IIRC there are several others here if you search plus see the suggested links at the bottom of this page.
If this is a homework project, I'll move it to the proper forum.

 

You'll have to be more specific, what exactly do you need help with?

It is clear, he needs help doing the project.

 

This has come up as a standard Homework question so many times that I don't know why there is any doubt.

 

Do you have to do this with PLC or PIC microcontrollers?

Assignment was probably do on the 2nd of March. You didn't come around soon enough. The poor kid had to decide if he will drop out or changes his major to ... (NOOOOOO!!!!!!), General Business or Psychology. If only you could have been here sooner.

 

This is enormously complex with switches and wires and little black things as well as LED displays and more wires.
I can help you with the wires.

 

Maybe the people designing elevator control systems should get together with the people who have burned-out treadmill circuit boards, and ... well, I'm not sure what they could accomplish. Something wonderful.

And experts on repairing LCD TV power supply boards (that were diagnosed to be bad by non-expert TV owners).

Interesting concept. Sounds like the setup of a good joke.

A an elevator repairman uses a treadmill motor to fix an elevator, now the car stands and...​

It would really freak out the user if the numerals would scroll from bottom to top.
