 * 1. Double-check your hardware connections match the pin assignments above
 * 2. Install required libraries (see LIBRARY_SETUP.md)
 * 3. Configure your WiFi credentials and IoT platform settings
 * 4. Upload this code to your ESP32
 * 5. Open Serial Monitor (115200 baud) to see system status
 * 6. Access web interface at http://[ESP32_IP_ADDRESS]
 * 7. Test your system with a small amount of water first!
 * 
 * WEB INTERFACE ACCESS:
 * - The ESP32 will display its IP address in the Serial Monitor
 * - Open a web browser and navigate to that IP address
 * - Use the configured username/password to log in
 * - Monitor your system and control irrigation remotely!
 * 
 * IOT PLATFORM ACCESS:
 * - ThingSpeak: https://thingspeak.com/channels/[YOUR_CHANNEL_ID]
 * - Adafruit IO: https://io.adafruit.com/[YOUR_USERNAME]/dashboards
 * 
 * TROUBLESHOOTING:
 * - If WiFi doesn't connect, check your SSID and password
 * - If sensors show invalid readings, check your wiring
 * - If pump doesn't activate, verify relay connections and power supply
 * - If LCD doesn't work, try changing LCD_ADDRESS from 0x27 to 0x3F
 * - If IoT uploads fail, verify your API keys and internet connection
 * - For more help, see the documentation or enable DEBUG_MODE
 * 
 * SAFETY REMINDER:
 * - Always test with small amounts of water first
 * - Monitor your system for the first few days
 * - Ensure proper drainage to prevent overwatering
 * - Use appropriate power supplies for your pump
 * - Keep your IoT credentials secure and change default passwords
