//HOW To control 4 RELAYS through Telegram Messenger with Telegram Bot

#include <ESP8266WiFi.h> // for ESP8266 Board

//#include <ESP8266WiFi.h>//Use for eso32 Board

#include <WiFiClientSecure.h>

#include <UniversalTelegramBot.h>

// Library for interacting with the Telegram API

// Search for "Telegegram" in the Library manager and install UniversalTelegramBot by Brian Lough

// https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot

#include <ArduinoJson.h>

// Library used for parsing Json from the API responses

// NOTE: There is a breaking change in the 6.x.x version,

// install the 5.x.x version instead

// Search for "Arduino Json" in the Arduino Library manager
