Final Project Proposal

Project Ideation

1- Tell us about the purpose of your project. Which problem does it solve? Why do you care about this? What were you inspired by? Include images and videos of similar projects

My project is called the Security Box.

Its goal is to create a secure and user-friendly storage box.
This project solves real problems with traditional key-based boxes (which can be lost or copied) and offers a custom, affordable alternative to expensive smart lock
I’ve always loved boxes, especially ones that are safe and secure, so I wanted to design one that looks great and also protects personal items like USB drives or small valuables.
I was inspired by DIY tech creators, real-world safes, and student projects, and I wanted to bring my own version to life, combining technology with creativity and woodwork

2- Describe the project idea and general features. How would it work?

My project is a Safety wooden box that uses an electronic lock controlled by an Arduino.
To open the box, the user needs to Enter the Correct password using a Keypad. There’s also an LCD Screen that shows instructions and feedback, a Buzzer for sound alerts, and a small Reset Button to change the password if needed.
All the Electronic Components are installed on the Inside of the door, so the Storage Space stays Clean and Organized.

The box itself is Designed in the shape of a House to give it a Unique and Artistic look.

3- Sketch your project: You may use pen and paper or a simple sketching tool like Microsoft Paint or Photoshop

Project Planning

4- Describe the Technical Modules that your project consists of

Construction Parts

I will design the structure from plywood in Fusion 360 and create custom brackets to join certain parts together

Input

(Sensing, Tactile Input, and/or Graphical Input)

Keypad

Reset Button

Action

(Physical and/or Graphic)

Physical Action:

Unlocking/Locking Mechanism: When the correct password is entered, the servo rotates to unlock the latch. If the password is incorrect, the servo stays in the locked position.

Sound Feedback: The Buzzer Emits different tones to indicate success (e.g. a short beep) or error (e.g. multiple beeps).

Graphic Actions:

Text Feedback:

1- "Enter Password" to inter the password

2- "Access Granted" if the password is correct

3- "Wrong Password" if the password is wrong

4- "Password Reset" to reset the password

5- Create a cardboard prototype of your project, demonstrating the project face as well as internal movements and mechanisms. Include a demo video and photos of the prototype.

6- Categorize your project’s User Features into: Minimum, Complete, and Nice-to-have features. List the required action and input components per feature.

Minimum Features: are the least amount of features that would demonstrate the coverage of all the technical modules and their complete integration
Complete Features: are the set of features that will complete your original project objective and vision
Nice-to-have Features: are the extra set of features that will make the project cooler, yet they need extra time, effort, and/or resources to finish

Minimum User Features

Feature: Password entry to unlock the box.

Action: User enters password on keypad.
Input Components: Keypad, Arduino.

Feature(A): Correct password triggers unlock.

Action: Play Success sound, display “Opened” message on LCD, RGB Led Green Light, unlock the door, and switch on the top inside lamp.
Input Components: Keypad (for entry), Arduino
Output Components: LCD (for display), Buzzer (for sound), RGB LED, Electric Solenoid Lock (for door), and the top inside lamp.

Feature(B): Incorrect password prevents unlocking.

Action: Play error sound, display “Incorrect Password” on LCD, RGB Led Red Light and Close door.
Input Components: Keypad, Arduino
Output Components: LCD (for display), Buzzer (for sound), RGB LED, Electric Solenoid Lock (for door).

Complete User Features

Feature: Password reset functionality.

Action: User presses the reset button to initiate the reset sequence. The RGB LED turns Blue to indicate reset mode. The user then enters a new password using the keypad.

Once the new password is successfully set, the RGB LED turns Purple.

Input Components: Keypad, Arduino, LCD (for confirmation), Push Button (For Reset)
Output Components: LCD (for display), Buzzer (for sound), RGB LED (Blue for reset mode, Purple for new password set), Electric Solenoid Lock (for door).

Nice-to-have User Features

Feature: Elevator-style smart key access.

Description: Similar to how elevators in secure buildings use smart keys or RFID cards to allow access to certain floors, the box would only unlock when a registered RFID/NFC key is scanned.
Action: User taps their smart key/card on the reader; if recognized, the box unlocks, otherwise, access is denied.
Input Components: RFID/NFC reader module, Arduino
Output Components: LCD (for status messages), Buzzer (for confirmation/error tones), Electric Solenoid Lock (for door), RGB LED (for visual indication)
