Smart Home Lighting System Manager

An end‑to‑end, fully automated home lighting system with feedback‑based control over interior and exterior LEDs.
Uses light (LDR) and motion (ultrasonic) sensing to drive auto-on/off and brightness, plus a VB.NET GUI for manual control and power estimation

🌱 Back Story

Our project originated from the need for a smarter, energy-efficient home electrical system. After conducting an analytical study that considered our team's background, available time, and tight schedule, we identified a problem: most home lighting circuits lack flexibility and real-time responsiveness. We created a system that adapts to ambient sunlight and motion to optimize energy use, using Rapid Application Development (RAD) in VB.NET alongside an Arduino-based sensing network.

As detailed in our proposal, this Smart Home Lighting System Manager automates LED control based on environmental feedback and provides per-room customization along with real-time power/current calculations.

🔧 Hardware Requirements

• Microcontroller: Arduino Uno
• Sensors & Actuators:
  • HC‑SR04 Ultrasonic Sensor (motion)
  • LDR Module (ambient light)
  • White LEDs (with 220 Ω current‑limiting resistors)
• Miscellaneous: Breadboard, jumper wires, USB cable, 5 V power supply

(The Wokwi simulation at https://wokwi.com/projects/430155215946846209 shows the exact wiring.)

🖥️ Software Prerequisites

• Arduino IDE (no extra libraries required)
• Visual Studio / VB.NET targeting .NET Framework 4.7.2 (or later)
• Guna.UI2.WinForms (latest NuGet package)

Application Interface

Modern VB.NET GUI built with Guna.UI2 framework for intuitive control and monitoring

⚙️ Installation & Setup

1. Build Hardware
   • Follow the wiring diagram in /Arduino/wiring-diagram.png or the Wokwi link above.
2. Flash Arduino
   • Open SmartHomeLight.ino in the Arduino IDE, select "Arduino Uno" and your COM port, then Upload.
3. Run VB.NET App
   • Open SmartHomeLight.sln in Visual Studio.
   • Restore NuGet packages (Guna.UI2.WinForms).
   • Compile & Run — the app will auto‑detect the Arduino's serial port.

📋 Usage

• Automatic Mode: LEDs respond to ambient light and motion, with adjustable brightness based on sensor readings—rooms light up at optimal levels without user input.
• Manual Mode: Use sliders and toggles in the GUI to control each room's LEDs individually—set on/off states and brightness per room.
• Dashboard: View live power/current readings and historical consumption graphs for each room and overall system.
