This tutorial of Robo India is a basic tutorial to connect a NodeMCU wifi module to the internet. This tutorial is based on Arduino IDE.
1. Introduction:
This tutorial explains how to connect a NodeMCU wifi development board to the internet. It connects to the internet through a wifi network.
1.2 Hardware required
| S.No. | Item | Quantity |
| 1 | NodeMCU | 1 |
| 2. | Micro USB cable | 1 |
2. Building Circuit
No circuit is required to run this tutorial. Just plug USB cable to the NodeMCU, upload the code provided here in this tutorial and its done.
3. Programming:
Here is the code to run this circuit on NodeMCU.
You may download this code (Arduino Sketch) from here.
#include <ESP8266WiFi.h>
const char *ssid = "Your wifi Network name"; // replace with your wifi ssid and wpa2 key
const char *pass = "Network password";
WiFiClient client;
void setup()
{
Serial.begin(9600);
delay(10);
Serial.println("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, pass);
while (WiFi.status() != WL_CONNECTED)
{
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
}
void loop()
{
}

My output only shows
“Connecting to (ssid)
…………………………………….” and so on with the dots.
Hello
Please check the SSID and password, you might have entered wrong.
I used above program but Node MCU is not getting connected to Wifi network. Getting an error ” Leaving
Hard resetting via RTS pin”
Looks correct. I enabled hot spot in my mobile…My computer is getting connected but node MCU not getting connected.
My output is also on serial port is
ssid…………………….
