yeBy using this system we can unlock the door by using pre-decided password, increase the
security level to prevent an unauthorized unlocking. In case the user forgets the combination of
password this system give the flexibility to the user to change or reset the password. This
automatic password based lock system will give user more secure yet cost-efficient way of
locking-unlocking system.
Firstly the user combination will be compared with prerecorded password stored in the system
memory. Our system will allow the user to go for certain number of wrong combinations before
the system will be temporarily disabled. But if user combination matches with the password, the
door will be unlocked. The same password can be used to lock the door. T
