A combination lock is a type of locking device in which a sequence of symbols, usually numbers, is used to open the lock. The sequence may be entered using a single rotating dial which interacts with several discs or cams, by using a set of several rotating discs with inscribed symbols which directly interact with the locking mechanism, or through an electronic or mechanical keypad. bination Lock Electronic Circuits and Projects ...
This circuit, based on the UA3730 IC with some modifiactions to produce a combination lock for a safe. The IC has many features which you can utilise but just a basic keypad and solenoid has been used for this design.
