Be more specific, what I want is:

1. passcode security lock to output on/off signal;

2. normal "off" output

3. when correct passcode is entered, output normal "on"

4. normal "on" lasts for pre-set time, says 30 seconds

5. multi passcodes can be stored and allow access for multi users

6. existing passcodes can be changed after entering correct passcodes

7. A "Master passcode" is maintained for administration such as resetting all passcodes and normal "on" time limit

8. error passcode input for 3 times shall deny all passcode input except "Master passcode".

Final deliverable shall be in complete assembly.
