Air Defense System- DIY Arduino Project-digilog.com.pk
Creating a DIY Air Defense System using Arduino is an exciting and educational project that blends electronics, programming, and basic robotics. While it won’t be a real military-grade system, it can simulate key defense functions like target detection, tracking, and response automation using sensors and actuators.Simulate an air defense system that detects incoming “threats” (e.g., toy drones or fast-moving objects) and responds by tracking or activating a countermeasure (like a laser, buzzer, or water gun).
| Component | Description |
|---|---|
| Arduino Uno/Nano | Microcontroller board |
| Servo Motors (x2) | For rotating turret (X and Y axes) |
| Ultrasonic Sensor | Distance detection (e.g., HC-SR04) |
| IR or PIR Sensor | Motion detection (optional) |
| Laser Diode or LED | For “firing” at the target |
| Buzzer | Alert system |
| Breadboard & Jumpers | For connections |
| 9V Battery or Power Bank | Power source |
| Mounting Hardware | Base, turret frame (3D printed or DIY wood/plastic) |
Basic Features:
-
Target Detection using Ultrasonic/IR sensors
-
Servo-Controlled Turret to aim at the object
-
Auto Fire/Response (LED blink, laser flash, or buzzer)
-
Alert System when threats enter a predefined range
🔌 Wiring Overview:
-
Servo motors connected to PWM pins on Arduino (e.g., D9 and D10)
-
Ultrasonic sensor (TRIG to D2, ECHO to D3)
-
Laser/LED or buzzer to D12
-
Power via 9V battery or USB
Optional Enhancements:
-
Add a camera module for vision-based detection (OpenCV + Raspberry Pi)
-
Use Bluetooth/Wi-Fi (ESP8266 or HC-05) for remote control
-
Implement radar simulation on OLED display
-
Add automatic tracking with more complex object location logic
Safety Notes:
-
Never point lasers at eyes or people.
-
This project is purely educational and not a real defense system.
