Detail's of Digital Door Lock using Moore Machine. 

     It describes the password locked door. I have taken a typical password "BAB" if somebody enters this password in door where the door admin have stored "BAB" as the password then the door unlock will be successful else it will not be unlocked. It describes the state diagram through Moore Machine. Moore Machine is a typical type of FSM representation where the output is related with the state i.e. it is represented inside the circle (the state). For the design of excitation table / state table universally accepted D flip-flop is used.
