can someone help how to build a simple code lock using timers as delay for switch activation and resetting.. thanks..

the schematic of the simple code lock i'm trying to tell can also be found here in allaboutcircuits.com

 

Here is a link to the post containing the circuit you are interested building, right?

This particular design does not contain a timer as part of the unlock sequence.
