   Download latest Blinker library here:
   https://github.com/blinker-iot/blinker-library/archive/master.zip


   Blinker is a cross-hardware, cross-platform solution for the IoT.
   It provides APP, device and server support,
   and uses public cloud services for data transmission and storage.
   It can be used in smart home, data monitoring and other fields
   to help users build Internet of Things projects better and faster.

   Make sure installed 2.5.0 or later ESP8266/Arduino package,
   if use ESP8266 with Blinker.
   https://github.com/esp8266/Arduino/releases

   Make sure installed 1.0.2 or later ESP32/Arduino package,
   if use ESP32 with Blinker.
