Write the 8051 assembly program code that will operate the following elevator circuit. From which floor the elevator is called, it will go to that floor and the floor number that the elevator passes will be displayed on the display and LEDs. It takes 1 second to pass between each floor. (Floor numbers decrease from top to bottom).

Repeat above (insert image) with the resistors in parallel, insert multitesters (digital or analog) to measure current along each resistor. Comment on the meter readings and set up.
