/* 
 *  Stephanie Wyckoff
 *  CSc 4110 - Embedded Systems
 *  Final Project - Running Clothes Barometer
 *  Due: 24 Apr 2018
 *  
 *  Description: This project sources real time weather data from OpenWeatherMap.org via an API key, is translated into 
 *    a useable format via the JSON parser, and that information is relayed to the user via lit up LEDs and LCD display.
 *    The bulk of this code came from the  ESP32 Weather Station Project v1.00, which can be found at 
 *    http://educ8s.tv/esp32-weather-station. I hava annotated which parts were wholy my own creation, which parts were 
 *    modified from the oritginal code and which parts are wholy the original code.
 *    
 *  Input: OpenWeatherMap.org weather information
 *  
 *  Output: Light up correct LED which is associated with the current weather (rain, wind, sun/clear, clouds) and also 
 *    update the LCD display from its default "Wifi Connecting..." to the coresponding image of running clothes or 
 *    incliment weather condition. 
 *
