📦 Features

• 🔊 Obstacle Alert System — Detects objects approaching from behind using an ultrasonic sensor.
• 🌡️ Overheat Detection — Monitors temperature via LM35 sensor and alerts on overheating.
• 🆘 Emergency Ignition System — FSM-based touch-start with timeout detection.
• 📍 Live GPS Tracking — Retrieves current location using NEO-6M GPS module.
• 📲 SMS Alert System — Sends automatic SMS via SIM800L during failures.
• 🖥️ LCD Feedback — Displays temperature, path status, ignition state.
• 🔔 Buzzer + LED Alerts — Visual + audio indicators for emergencies.

🚀 How to Run

1. Connect Your Hardware exactly as shown in the wiring diagram.
2. Install Libraries:
   • Open Arduino IDE.
   • Go to Sketch > Include Library > Manage Libraries.
   • Search and install:
     • LiquidCrystal_I2C
     • SoftwareSerial
     • TinyGPS++
3. Set Board & Port:
   • Tools > Board > Arduino Uno.
   • Tools > Port > Your Arduino Port.
4. Upload the Code:
   • Open ekart_safety_system.ino.
   • Replace +91XXXXXXXXXX with your actual phone number.
   • Click the ✅ Verify button.
   • Click the ⬆️ Upload button.

When powered, the LCD should display status messages and sensors will initialize.

✅ Requirements

Install the following libraries via Library Manager:

• LiquidCrystal_I2C
• SoftwareSerial
• TinyGPS++

---

📝 Notes

• Make sure your SIM card is activated and unlocked (no PIN).
• The GPS module must be outdoors or near a window to get a signal.
• You can adjust sensor thresholds in the code:
  • distanceThreshold
  • tempThreshold
  • emergencyTimeout
