Introdution ESP8266 With Node MCU

I  am going to give you the introduction of ESP8266 microcontroller.
How to get started with this ESP8266?
We are going to use here the Arduino IDE to write custom firmware that is gonna be download on the board & execute it.
The material required for this tutorial are:-

  1. The micro USB cables.
  2. The ESP8266 development board with translator chip by silicon lab.
  3. Yeah, I have taken this solderless breadboard because it is easy to use & I prefer this.
  4. Another thing we require is the ESP12e module.
we are going to need the Node MCU Lua ESP12e ESP8266 Wifi development board. This is the open source IoT platform.

It has several benefits of using this board like it is having necessary circuitry to manage the voltages.

And it is really very good that it manages 3.3v on the board. The USB to UART interfacing makes it very simpler to connect the computer.

To configure ESP8266 we are going to use the AT commands are sent via serial UART interface. this is the list of AT commands.

I will tell you how to configure the ESP8266 with AT commands in the next tutorial.

Arduino IDE is compatible with ESP8266 node MCU. Now go to the Arduino.cc website for downloading this software.

This file is better for windows. Depending on the OS, you can download.it will take a few minutes to download.

I have already downloaded this one.
For connecting USB to ESP8266, we need a USB to UART bridge driver. which is downloaded from silicon labs.

if we are not having the driver installed, it indicates a yellow triangle for downloading the driver,go through the silabs.com, (site a silicon lab. &download as per your os)
let us check the driver if it is installed or not, right click on computer→ manage →device manager→ports.

here silicon lab is already installed. you can also check further properties.
install both the software.

for that Open the Arduino go to file→preferences.
Additional boards manager URLs.
