Task $2$:

Design a Finite State Machine $($FSM$)$ for a smart house lock that unlocks when the passcode. The lock system is only accepting $6$ digits passcode number. It allowed for $3$ times of passcode attempt, if not, the system will ask the user to reset the passcode and the system will be in "locked" states until it been reset.

Your design should include:

i$.$ State diagram

ii$.$ Next State truth table & state assignment

iii. K$-$map

iv$.$ Circuit Diagram

v$.$ Circuit simulation using Multisim

Hint: Please assign the passcode before proceed with the design.
