Electronic Combination Lock

This circuit is very
basic to build. To open a the lock which is connected to the K1 Load you
must press each momentary switch in the correct sequence. The sequence
used in this circuit is S1,S2,S3,S4. If any of the other switches are
pressed the circuit will reset and you will need to start over.
Depending on how you wire the switches, you can use any 4 switch
