How to use NodeMCU Getting started with NodeMcu the Basics

Welcome to the first Tutorial of NodeMcu. In this tutorial, we will learn about NodeMcu board.Why we use the NodeMcu. How to use NodeMcu and installation of NodeMcu with Arduino IDE. We will see some projects with NodeMcu after first 10 basic Tutorials.
So here are the Contents for today:

Step: 02Why  to Use NodeMcu

Step: 04Specification

Follow the steps to install the NodeMcu setup in Arduino IDE:

Step # 01:

File tab and then click on Preferences:
Boards Manager URLs add the following link :

http://arduino.esp8266.com/stable/package_esp8266com_index.json

Step # 02:

Tools > Boards  >  Boards Manager

Now in the search field type :

esp8266 > click the link esp8266 by ESP8266 Community  > Click Install

Final Step:

Now  Go to the Boards and in the list select the NodeMCU 1.0  the (ESP-12E Module).

Now that’s it! We have installed the setup for NodeMcu. Select the NodeMcu board same as we select for Arduino boards like nano, Uno or Mega. Select Esp-12E module this time.

If the Arduino IDE doesn’t recognize the port for  NodeMcu update the drivers from the Device manager.

Step: 06Circuit Diagram:

For the testing the board Go to the examples and Run a simple Blink Code :

Step: 07Code for NodeMcu

.......   void setup() { .......    // digital pin 13 as an output. ...........     pinMode(13, OUTPUT); } .......   void loop() { ........    digitalWrite(13, HIGH);   //HIGH is the voltage level ...........    delay(1000);              // wait for a second ...........      digitalWrite(13, LOW);    //  voltage LOW ...........       delay(1000); }

1 2 3 4 5 6 7 8 9 10 11

.......   void setup() { .......    // digital pin 13 as an output. ...........     pinMode(13, OUTPUT); }   .......   void loop() { ........    digitalWrite(13, HIGH);   //HIGH is the voltage level ...........    delay(1000);              // wait for a second ...........      digitalWrite(13, LOW);    //  voltage LOW ...........       delay(1000); }
