/*
 * ovim programom povezujemo ESP8266 ESP-01 sa ARDUINO UNO-M i sa wi-fi mrezom
 * arduino je povezan sa usb-om na kompjuter, a ESP8266 ESP-01 je povezan na sledeći način:
 * gnd na gnd
 * Rx preko naponskog razdelnika (5V na 3,3V) je povezan na arduino pin 3
 * Tx je povezan na arduino pin 2
 * Vcc, Reset i CH_PD je povezan na +3,3V
 * GPIO_0 nije spojen nigde

 **************************************************************
 *
 * This example shows how to use ESP8266 Shield via Software Serial
 * (on Uno, Nano...) to connect your project to Blynk.
 *
 * Note: Ensure a stable serial connection to ESP8266!
 *       Firmware version 1.0.0 (AT v0.22) or later is needed.
 *       Set ESP baud rate to 9600. Connect to AT console and call:
 *           AT+UART_DEF=9600,8,1,0,0
 *       In general, Soft Serial is unstable.
 *       It is highly recommended to switch to Hard Serial.
 *
 * Change WiFi ssid, pass, and Blynk auth token to run :)
 * Feel free to apply it to any other example. It's simple!
