A-SLA02 - Smart Motion Detection Alarm System

🔧 Key Components &
Functions:

• Arduino
  Uno: The brain of the system, responsible for processing sensor inputs
  and controlling outputs.

• PIR
  Motion Sensor: Detects motion in the surroundings. When triggered, it
  alerts the system.

• 16x2
  LCD Display: Shows live status messages like “MOTION DETECTED” or
  “SYSTEM ARMED”.

• Buzzer:
  Sounds an alarm when motion is detected to warn intruders or alert users.

• RGB
  LED:

• 🔴
  Red – Motion detected and alarm activated.

mso-bidi-font-family:"Segoe UI Emoji"">⚙️ How It Works:

1. On
   powering up, the LCD displays a welcome message and enters monitoring
   mode.

1. The
   system continuously checks for motion using the PIR sensor.

1. When
   motion is detected:

• The
  buzzer sounds an alarm.

• The
  RGB LED turns Red.

• The
  LCD displays “MOTION DETECTED”.

1. When
   no motion is detected:

• The
  system stays on guard.

• The
  RGB LED shows Green or Blue depending on mode.

• The
  LCD shows “NO MOTION DETECTED”.

• Home
  and office security

• Smart
  door alert systems

• Motion-based
  alert systems in restricted zones

This smart alarm system is a great DIY project to learn
about sensor integration, real-time feedback, and Arduino-based
automation.
