You need to tell us a lot more about this project. How are you moving the car? Are there limit switches at each floor? Are there call buttons (up and down) at each floor? What Arduino are you using? Are there 7 segment displays at each floor?
What IC are you planning to use? How will that reduce the number of wires?
so i'm waiting for ur helps and guides about the programming it and creating the circuit.
Spelling help, too?
What problems are you having? What is the goal of the project?
Have you looked at how a real elevator is constructed/wired/controlled?
