AI-Based Smart Security System 🔐🤖

An Arduino-based smart home security system that detects motion using a PIR sensor and responds to AI-style commands via Serial Monitor.

---

🚀 Features

• Motion detection using PIR sensor
• AI-style commands via Serial Monitor
• Visual and sound alerts (LED & Buzzer)
• Silent mode for non-intrusive alerts
• Fully simulated using Tinkercad

💡 AI-Inspired Logic

The system accepts the following commands via Serial Monitor to simulate AI control:

Command	Function
alert	Manually trigger alarm
silent	Enable silent mode (no buzzer sound)
on	Re-enable system after turning it off
off	Disable system (no motion detection)
