Aim:
To design, build, and present a working prototype of a smart device that addresses a real-life problem.

Requirements:

• Arduino or Raspberry Pi Pico

• At least 2 different sensors (e.g., PIR motion sensor, LDR, temperature sensor, ultrasonic sensor)

• At least 1 output device (buzzer, LED, motor, relay)

• USB cable for programming

• Poster or slide presentation for explaining the project

Procedure (Step-by-Step)

1. Identify a Problem
   • Look around your home, school, or community.

   • Find an issue that could be solved using automation or sensors.

   • Examples:
     • Automatic waste detection in dustbins

     • Energy-saving lighting system

     • Water level monitoring for tanks

2. Design Your Solution
   • Decide what sensors and outputs will be used.

   • Draw a rough circuit diagram and plan your wiring.

   • Write down the logic flow — e.g., “If motion is detected AND light is low, then turn ON the lamp.”

3. Build Your Prototype
   • Assemble your hardware on a breadboard or PCB.

   • Connect the sensors, outputs, and microcontroller.

   • Upload your code and test each part separately before running the full system.

4. Test and Improve
   • Check if your device works as expected.

   • Make improvements for accuracy, speed, or reliability.

5. Prepare Your Presentation
   • Create a poster or slides showing:
     • The problem

     • Your solution

     • How it works (with photos or diagrams)

     • Benefits of your device

   • Practice explaining your project in under 3 minutes.

6. Showcase Your Project
   • Present to your classmates, teachers, or a panel of judges.
   • Answer questions confidently.
