/****************************************************************************************************************************
   WiFi & BLE Control Home Automation using ESP32 and Blynk

   Required Library:
      Blynk library v0.6.1 https://github.com/blynkkk/blynk-library/releases
      BlynkESP32_BT_WF by Khoi Hoang https://github.com/khoih-prog/BlynkESP32_BT_WF-             Pls install the old version
      Based on orignal code by Crosswalkersam https://community.blynk.cc/u/Crosswalkersam

   The Sketch is Modified by Sayantan Pal https://github.com/palsayantan/12-ch-Ultimate-Home-Automation-using-ESP32

*****************************************************************************************************************************
   Important Notes:
      This code is intended to run on the ESP32 platform!
      Check your Tools->Board setting. And select ESP32 Dev Module
      To conmpile, use Partition Scheem with large APP size, such as -- Huge APP (3MB No OTA, 1MB SPIFFS)
