How to Submit Submit your work to the D2L Assignment Folder: Homework 4. Please provide a digital copy of your work (e.g., scan, screenshot, .PDF, etc.) Please provide a description so that we can understand your design when we grade it. Problems 1. Create a State Machine Diagram and a State Machine Table for the following door combination lock: a. A simple door combination lock consists of punching in a sequence of 4 keys. b. The door lock has at least 5 states: i. Locked, initial state with no correct combination entered, ii. Locked Combo1, where the first combination has been entered correctly, i. Locked Combo2, where the second combination has been entered correctly and is only reached immediately following LockedComboi, iv. Locked Combo3, where the third combination has been entered correctly, and is only reached immediately following LockedCombol and LockedCombo2, and V. Unlocked c. The lock opens (becomes unlocked) when the 4-key sequence is correct. i. Once unlocked, the lock automatically resets after 3 seconds. d. The lock is reset if the input value incorrect and returns to the initial state, Locked. e. If the time between any sequence entry is greater than 3 seconds, then the lock is reset and returns to the initial state, Locked. f. The Reset button, no matter where we are in our sequence, resets the sequence to the initial state. & The combination to the lock is 2019, and must be entered in that sequence (i.e., 2-0-1-9).
