Every person needs to feel safe in their daily lives. Access control for doors is an important part of our security plan. Password-protected door locks let only approved people into restricted places. Normal locks aren't as safe as they used to be; anyone can get in if they get past these locks. Our system needs to work 24 hours a day, seven days a week. A board called an Arduino runs it. A keyboard is used to enter the password. The typed password is compared to the known password when a mixture password or a password with 1 to 6 digits is set. With the right password, the door opens and the condition is shown on the LCD. The door stays shut and the LCD screen shows "WRONG PASSWORD" if the password is wrong. The buzzer will also go off an infinite number of times when the wrong password is entered. Electronic door locks will be used instead of mechanical ones in the security door locking system. This is a big step forward for the future.
