This example demonstrates how to use the TCP client 
functionality of the ESP8266 WiFiSecure library to GET 
data to a EggTimer on 
https://eggtimer.herokuapp.com
Development environment specifics:
  IDE: Arduino 1.6.5
  Hardware Platform:
  ESP8266 HUZZAH Adafruit
  or NodeMCU: 1.0

This code is beerware; if you see me (or any other The Inventor's House 
member) at the local, and you've found our code helpful, 
please buy us a round!

great, thank you!
