    ESP8266 Wifi Smart Home IOT For Arduino DIY Kit
    ESP8266 Esp-01 Serial Port WIFI Transceiver Wireless Module
    ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete
    and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi
    networking functions from another application processor.
    ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the
    sensors and other application specific devices through its GPIOs with minimal development up-front and
    minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry,
    and the entire solution, including front-end module, is designed to occupy minimal PCB area.

    Now your Arduino can get on WiFI without braking the bank.
    Use this module for your next Interet of Things project, home automation, Or remote sensor project.
    This module adats the ESP8226 IC for use over a serial connection using simple AT commands.
    No SPI interface or Know-How is required.
    Warnings:
    This module requires a 3.3 volt supply for VCC, and 3.3V logic. It is not 5V tolant. Connect RX or TX on 5V Arduino will
    destroy this module. You must use a logic level converter, or a 3.3V Arduino
    The 3.3V supply on the Arduino Uno has inadequate current capabilit to power this module. You must provide a separate,
    higher 3.3V supply(about 300mA or better)
    The ESP8225 module is very new on the market and support and documentation for it is currently very limited.
