Smart AC Power Modulation Using Zero-Cross Detection with Live LCD Display

This project is about building a smart and efficient AC power control system that uses zero-cross detection for safe switching and an LCD display to show real-time system status.

📌 Main Objectives:

⚡ Zero-Cross Detection: Detects the exact point where AC voltage crosses zero, allowing safe and precise switching of electrical loads with minimal sparks or noise.

🔁 Power Modulation: Controls how much power is sent to connected devices, making it suitable for applications like light dimming, fan speed control, or industrial heating.

📺 Real-Time LCD Interface: A user-friendly LCD screen shows current voltage levels, switching status, and other system parameters in real-time.

🧠 Microcontroller-Controlled: Powered by a smart controller (e.g., STM32 or Arduino) that ensures accurate timing and smooth power delivery.

🔒 Safe and Efficient: Designed to minimize energy loss, avoid overheating, and improve the overall safety of power systems.

🎯 Applications

• Home automation (smart fans, dimmable lights)

• Industrial temperature control systems

• Smart energy-saving devices

• Educational and research labs.
