🕵️‍♂️ The Invisible Guard: PIR Motion Burglar Alarm System | My First Logic Kit

Upgrade your home security with infrared technology! Using the MB-54 Multi-Sensor Kit V3.0, this project builds a smart "Burglar Alarm" that triggers an LED lamp and buzzer the moment it senses movement. 🚨💡

How it works:
The PIR (Passive Infrared) Sensor scans for heat signatures from humans or pets.
🔹 Movement Detected: The N/C USB terminal activates → Lamp turns ON & buzzer SOUNDS!
🔹 No Movement: The circuit remains idle → Lamp & buzzer stays OFF.

Features:
✅ Customizable Control: Two onboard knobs to adjust Sensitivity (range) and Time (how long the light stays on).
✅ Clockwise 🔄: Increases sensitivity and extends the timer.
✅ Counter-Clockwise 🔄: Lowers sensitivity and shortens the timer.
✅ Security Logic: A perfect reference for the "My First Logic Kit" guide.
