Hello all,
I've received a project to simulate an Elevator operation with 8085 Microprocessor. Elevator function is to be shown using LEDs and switch corresponding to each floor.
Functioning is as follows:
1. There are 4 levels(floors) and corresponding to each level an LED and a switch is provided. Also, there are two separate LEDs which indicate whether the lift is going up or down.
2. Initially, the lift is at ground floor (reference level). When a request is made by a user from other floor, say 2nd floor, lift moves to that floor and movement of lift is shown by turning on LEDs of floors as it crosses the respective floor and then turning them off as lift reaches next floor. When lift reaches 2nd floor, corresponding LED turns on and remains as such until further request is made by user.
3. Now, the user has embarked the lift and presses the button corresponding the floor where he wants to go, say 3rd floor, so the lift moves to 3rd floor and stays there until another request is made and hence it continues as such. (Please note that, here, only one switch is corresponding to each floor, so it is assumed that when the next switch is pressed, it indicates where the user wants to go).

Does anyone have any useful information regarding how it can be implemented using 8085 microprocessor?

Thanks in advance!

 

Step 1.
Draw some kind of diagram, a flow chart would be good.

 

Do a search on this forum; Elevators come up at least twice a year as they are common school projects.

How come the 8085 interest has increased so much just in few days

 

A teacher in India has handed out the project assignments to his students. We see this around this time every year.
