/*
* CONGRATULATIONS! Your IoT smart farming system is now configured.
*
* NEXT STEPS:
* 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
