🏍️ ESP32 Smart Motorcycle System with Auto-Off & Anti-Theft

This project is a smart motorcycle security and control system based on the ESP32 microcontroller. It features Bluetooth control, multi-mode relay activation, and an anti-theft system that triggers an alarm if the vehicle is moved while in parking mode.

🔧 Features

• 🔌 3 Relay Control Modes

  • Relay 1 (ON/OFF toggle)
  • Relay 2 (Push-to-ON, active while pressed)
  • Relay 3 (Toggle + Auto-off after a delay + Alarm mode)

• 📱 Bluetooth Control via MIT App Inventor

• 🅿️ Parking Mode Detection
  If the Bluetooth connection is lost, the system enters parking mode and watches for movement.

• 🚨 Anti-Theft Alarm
  If movement is detected during parking mode (via MPU-6050), the alarm relay is triggered for 1 minute.

• 🔋 Auto-Off Function
  Relay 3 automatically turns off after a set duration if no action is taken.

🚀 How to Use

1. Upload the Code

Flash motor_iyus_auto_off.ino to your ESP32 using Arduino IDE or PlatformIO.

2. Connect the Hardware

• Wire the relays, LED, buzzer, and MPU-6050 according to the diagram above.
• Ensure ESP32 has a stable 5V power supply.

3. Build the Android App

• Use MIT App Inventor to create an app with 3 buttons:
  • Button 1: Toggle Relay 1
  • Button 2: Momentary Push Relay 2
  • Button 3: Toggle Relay 3 + enable auto-off + alarm

(I can help design the UI if needed!)

4. Pair Phone via Bluetooth

• Connect your Android phone via Bluetooth to the ESP32 module.
• Control the system using the app.

5. Auto-Off and Alarm

• When Relay 3 is turned ON, a timer begins.
• If Bluetooth disconnects (simulating parking), system enters parking mode.
• If movement is detected by MPU-6050, the alarm will activate for 1 minute.

📌 Notes

• The system is designed to continue functioning after Bluetooth disconnect.
• You can modify the delay time for auto-off or alarm duration in the code.
• Always ensure power safety when connecting to real motorcycle circuits.
