This is a simple code for interfacing IoT shield with Blynk app using Arduino IDE
/**************ed************************************************
 * This code is to be used for ARMA IoT hardware. It is open source.
 * You can easily build graphic interfaces for all your
 * projects by simply dragging and dropping widgets.

 **************************************************************
 *
 * This example shows how to use ESP8266 Shield (with AT commands)
 * to connect your project to Blynk.
 *
 * Note: Ensure a stable serial connection to ESP8266!
 *       Firmware version 1.0.0 (AT v0.22) is needed.
 *       You can change ESP baud rate. Connect to AT console and call:
 *           AT+UART_DEF=9600,8,1,0,0
 *       In general, Soft Serial may be 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!
