im planning a project that consists of a code circuit (for a safe say) but have no idea where to start.
i would like to have a code of about six numbers with two attempts at getting the correct code. If the code isnt correct an alarm should go off with an audible output.
if the correct code is guessed it will turn off an electromagnet and open the safe but only after a time delay of 3 minutes say
i have no idea how to approach this so any help with links or circuit diagrams is much appreciated
