It is also cheap and be used for making cool projects connected to the Internet .Learn how to make a simple IOT Project with it .The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers (and that’s just out of the box)! The ESP8266 module is an extremely cost effective board with a huge, and ever growing, community.

Step 1: Components and Connection

Components and Connection Thing we will need

ESP8266 Pinouts

Vcc -power supply 3.3 v

Gnd – Ground

RST- reset

CH-PD-Chip power Down- Connected to 3.3V


Tx – Transmit

GPIO 0- Normal mode for HIGH Programming Mode for LOW

GPIO 2 General purpose 2

Step 2: Making the Esp 8266 Bread Board FriendlyComponents and Connection 4


Components and Connection 2

Esp 8266 esp 1 is badly famous for being rude to the Bread board .

Here is a small hack to make it convert into a DIP pack.

You only want a 4x 4holes perf section with 4 rows of copper track of length four holes.

see the photos and you’d understand what I mean by that.

Cut two Strips of 4 Male Header pins each.

Cut two Strips of 4 Female Header pins each.

Push the 4-Pin Female header pins

Solder the Female Header (4-Pins each)

Push the 4 pin male all the way down until they are invisible in one side of the plastic frame.

Solder the male Header (4-Pins each) and join female together with it


Vcc and ch_pd to vcc

Gnd to gnd

Rst to button 1

GPIO0 to button 2

Note While uploading Program press reset once while holding GPIO Button as long as the program uploads.

Step 3: Setting Up the Arduino Environment

Setting Up the Arduino Environment.You need to download the core if your Arduino is below 1.6

Installing with Boards Manager for Arduino

Starting with 1.6.4, Arduino allows installation of third-party platform packages using Boards Manager. We have packages available for Windows, Mac OS, and Linux (32 and 64 bit).

  • Install Arduino 1.6.8 from the Arduino website.Start Arduino and open Preferences window.
  • Enter… into Additional Board Manager URLs field.
  • You can add multiple URLs, separating them with commas.
  • Open Boards Manager from Tools > Board menu and install esp8266 platform (and don’t forget to select your ESP8266 board from Tools > Board menu after installation).

TThe led is connected to the GPIO 2

Tx is connected to Rx
Rx is connected to Tx

Ch_pd to 3.3v

GPIO 0 to gnd while programing

int ledPin=2;

void setup() {
pinMode(ledPin, OUTPUT);

void loop() {
digitalWrite(ledPin, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(ledPin, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
