//By Jeremy S. Cook - controls a few LEDs meant for a Pumpkin

//based on relay demo by Innovative Tom:

//That code in turn was resued from the example on the ESP8266 Learning Webpage below: 
//http://www.esp8266learning.com/wemos-webserver-example.php

//CODE START 

#include <ESP8266WiFi.h>

// Below you will need to use your own WIFI information.

const char* ssid = "XXXYYY"; //WIFI Name, WeMo will only connect to a 2.4GHz network.
const char* password = "ABC123"; //WIFI Password

//defining the pins and setting up the "server"3

int Light1 = D1; // System uses pin 1 for first LED
int Light2 = D2; // System uses pin 2 for second LED

WiFiServer server(80);
IPAddress ip(10, 0, 0, 99); // where xx is the desired IP Address
IPAddress gateway(10, 0, 0, 1); // set gateway to match your network
IPAddress subnet(255, 255, 255, 0); // set subnet mask to match your network


// void setup is where we initialize variables, pin modes, start using libraries, etc. 
//The setup function will only run once, after each powerup or reset of the wemos board.
