ESP8266 - Wi-Fi Module Content 1 Introduction 2 Features of ESP8266 3 How to Interface ESP8266 with Arduino Uno 3.1 Hardware and Software required 3.2 Circuit Diagram 6 Program for ESP8266 Introduction to ESP8266 The ESP8266 Wi - Fi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any micro - controller access to your Wi - Fi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor.This module has a powerful enough on-board processing and storage capability that allows it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during run - time. Its high degree of on-chip integration allows for minimal external circuitry, including the0front-end module, is designed to occupy minimal PCB area. The ESP8266 supports APSD for VoIP

7400 - Quad Two Input NAND Gate 74LS00 is part of the 74XXYY IC series. 74xxyy integrated circuits are logical gates of digital electronics. The 74LS00 IC has four NAND gates(NAND Gate is the combination of AND and NOT Gate). In addition, each door has two entrances. Hence the name QUAD TWO INPUT NAND GATE.     Pin Diagram of 7400 IC 74LS00 is a 14-pin device. The chip is available in different packages and is chosen according to the needs.  The description of each pin is given below.
