$1-$ Connect a $4$x$4$ Keypad and an LCD to the $8051.$

$2-$ Write a program that prompts the user to enter an $8-$digit password from the keypad. The program will then check the password entered against the password table stored in ROM memory. If it matches one of them then a welcome message and the corresponding user name will be displayed on LCD, otherwise, an incorrect message will be displayed and the user will have to enter the password again.

Let us assume that $10$ passwords and usernames are stored in ROM.

For example

$01234567$ ali

$87654321$ ayse

$45663211$ mehmet

$..............$

So if the user enters $01234567,$ the system should display "Welcome ali" on LCD
