Blynk is a platform with iOS and Android apps to control
Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your
projects by simply dragging and dropping widgets.

This example code is in public domain.
**************************************************************************************************
This example runs directly on NodeMCU.
Note: This requires ESP8266 support package:
https://github.com/esp8266/Arduino
Please be sure to select the right NodeMCU module
in the Tools -> Board menu!
For advanced settings please follow ESP examples :
- ESP8266_Standalone_Manual_IP.ino
- ESP8266_Standalone_SmartConfig.ino
- ESP8266_Standalone_SSL.ino
Change WiFi ssid, pass, and Blynk auth token to run :)
Feel free to apply it to any other example. It's simple!
