Objective:$$Design and implement a digital lock system using both combinational and sequential circuits.

Project Description:$$Designing a digital lock system where a specific sequence of inputs $($like a combination code$)$ must be entered correctly to unlock a digital lock. The system will have the following components:

Input Unit:$$Keypad or switch matrix to enter the combination.

Control Unit:$$Handles the sequence of inputs and determines if the correct sequence has been entered.

Output Unit:$$Indicates whether the lock is in the locked or unlocked state using LEDs or a display.

Components and Requirements:

Input Unit:

Design a keypad matrix or a set of switches for input.Each key press should generate a unique binary code.

Control Unit:

Use combinational logic to decode the inputs from the keypad.Implement a finite state machine $($FSM$)$ using sequential circuits to handle the input sequence.The FSM should move through states based on the sequence of inputs and determine if the correct combination has been entered.

Output Unit:

Use LEDs or a $7-$segment display to show the lock status $($locked$/$unlocked$).$Implement a reset mechanism to re$-$lock the system after a certain period of inactivity or after an incorrect combination is entered.

Deliverables:

Design Documentation:

Schematic diagrams of the combinational and sequential circuits.State diagrams and truth tables for the FSM$.$Detailed explanation of the design and how each part works.

Simulation:

Use software tools $($like Multisim, Logisim, or any other digital circuit simulation tool$)$ to simulate the circuit.Demonstrate the working of the lock system through the simulation.

Prototype $($Optional$)$:

Build a physical prototype using digital logic ICs or a microcontroller $($e$.$g$.,$ Arduino$).$Demonstrate the working prototype to the class.

Report and Presentation:

Write a final report summarizing the project, design process, challenges faced, and solutions implemented.Prepare a presentation to showcase the project to the class.

Evaluation Criteria:

Correctness and completeness of the design.

Functionality and reliability of the simulation$/$prototype$.$

Clarity and thoroughness of the documentation and report.

Quality of the presentation and ability to explain the project.
