  1. /*
  2.  Basic ESP8266 MQTT example
  3.  This sketch demonstrates the capabilities of the pubsub library in combination
  4.  with the ESP8266 board/library.
  5.  It connects to an MQTT server then:
  6.   - publishes "hello world" to the topic "outTopic" every two seconds
  7.   - subscribes to the topic "inTopic", printing out any messages
  8.     it receives. NB - it assumes the received payloads are strings not binary
  9.   - If the first character of the topic "inTopic" is an 1, switch ON the ESP Led,
  10.     else switch it off
  11.  It will reconnect to the server if the connection is lost using a blocking
  12.  reconnect function. See the 'mqtt_reconnect_nonblocking' example for how to
  13.  achieve the same result without blocking the main loop.
  14.  To install the ESP8266 board, (using Arduino 1.6.4+):
  15.   - Add the following 3rd party board manager under "File -> Preferences -> Additional Boards Manager URLs":
  16.        http://arduino.esp8266.com/stable/package_esp8266com_index.json
  17.   - Open the "Tools -> Board -> Board Manager" and click install for the ESP8266"
  18.   - Select your ESP8266 in "Tools -> Board"
