Write an Arduino program to design a password lock, which takes input from a $4$x$4$ matrix keypad. Use an RGB LED to show login status. The LED color should be blue while accepting the password from the user. If the wrong password is given and you attempt to log in$,$ the LED should flash Red four times. Upon a successful password, the LED should turn green for two seconds. After two seconds, the LED should flash green and start accepting the new password again. Use your student ID as the password for successful login$.$ Start the program by printing $$####$.$

Your code should also display the login status and all the steps in the serial monitor. Display a meaningful message in the Serial monitor upon successful login$.$

You may use any of the following $(*,$ #$,$ A$,$ B$,$ C$,$ D$)$ keys as enter key, clear key, or reset login key.
