system gives solution to that problem. This circuit described here activates only when the specified sequence of four digits is pressed. If a wrong key is touched‚ it will not unlock. The lock code is set by connecting nine SPST switches. The code lock circuit is built around two CD4013 dual-D flip-flop ICs. The clock pins of the four flip-flops are connected to that specified sequence of digits‚ which is the correct code sequence to unlock the system. The circuit also contains (555) timer IC to lock automatically
