six valid input keys, unlock Sl ~ S6 must comply with this order; feet have connected key switch S7 is false key input, you can freely access one or a few keys on the keyboard mixed into real ones; a feet is the key indicator pin during each key communication will make the external light emitting diode emitting LEDl confirm that the key input is valid; ? feet alarm an output terminal, if not by Sl ~ S6 sequentially input or exceed the effective unlocking time, the output high, burglar alarm trigger IC2 language effectively unlocking time by the size of the capacitor C1 and potentiometer RPl to decide.
