Objective: Design and construct an interactive puzzle box that incorporates various sensors and output devices, controlled by an Arduino. The puzzle box should require the user to complete a series of tasks involving light, sound, and distance sensors to unlock it. Creativity in the design and complexity of the tasks is encouraged to test the user’s problem-solving skills and understanding of embedded systems.

## Project Requirements:

### 1. Design Overview:

– The box must include at least four distinct steps that need to be completed in sequence to unlock it.
– Each step should involve interaction with different sensors or input devices (e.g., distance sensors, sound sensors, switches).
– Provide visual or auditory feedback to the user upon the completion of each step using LEDs or sounds.

### 2. Technical Components:

– **Arduino Microcontroller:** Use as the brain of the puzzle box to control all inputs and outputs.
– **Sensors and Inputs:** Must include a distance sensor, sound sensor, and at least two other types of sensors or input devices of your choice.
– **Outputs:** Must include LEDs for visual feedback and a small motor to unlock the box upon completion.
– **Power Source:** Design a safe and reliable power source for the box.

### 3. Functionality:

– **Reset Feature:** Incorporate a switch to reset the puzzle at any stage.
– **Cheat Prevention:** Implement measures to prevent bypassing the intended puzzle-solving process.
– **User Interaction:** Design the puzzle to be engaging and intuitive for the user. Instructions or hints may be provided, but the primary goal is for the user to explore and discover how to solve the puzzle.

### 4. Construction:

– **Enclosure:** Design and build an enclosure for the puzzle box that is sturdy and aesthetically pleasing.
– **Internal Organization:** Carefully organize and secure the internal components for durability and ease of maintenance.
