 * Title: Simple ESP-8266 Wifi RGB LED Strip Light Controller
 * File: esp8266_rgb_led_controller.ino
 * Author: James Eli
 * Date: 1/14/2018
 *
 * Blynk slider #1 (r) GPIO14
 * Blynk slider #2 (g) GPIO05
 * Blynk slider #3 (b) GPIO12
 * 
 * This program controls an RGB LED strip light. 
 * 
 * Notes:
 *  (1) Requires the following arduino libraries:
 *      ESP8266
 *  (2) Compiled with arduino ide 1.8.3
 *  (4) To place an ESP8266 into program mode, GPIO0 must be LOW during power up. 
 *  (5) Test Pads on PCB back:
 *        #1 – GND
 *        #2 – Pin #12 IO00
 *        TX – Pin #16 TX
 *        RX – Pin #15 RX
