How to Know the NodeMCU IP Address for Your Next IoT Project

 NodeMCU IP Address: The NodeMCU is a popular development board for IoT projects. It’s small, affordable, and comes with built-in Wi-Fi connectivity, making it the perfect choice for creating connected devices. But before you can start building your NodeMCU projects, you need to know the IP address of your device.

This IP address is essential for communicating with the NodeMCU from another device, such as a computer or smartphone. In this article, we’ll show you how to find the NodeMCU IP address, so you can get started with your next IoT project.

Method 1: To Know the NodeMCU IP Address

One of the easiest ways to find the NodeMCU IP address is by using the serial monitor in the Arduino IDE. First, connect your NodeMCU board to your computer using a micro-USB cable. Then, upload the following code to the NodeMCU:

#include <ESP8266WiFi.h>

void setup() {
  Serial.begin(115200);
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println("<WiFi SSID>");

  WiFi.begin("<WiFi SSID>", "<WiFi Password>");
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.print(".");
  }

  Serial.println();
  Serial.print("Connected, IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
}

Replace <WiFi SSID> and <WiFi Password> with the credentials for your Wi-Fi network. After uploading the code, open the serial monitor in the Arduino IDE. You should see the NodeMCU connecting to your Wi-Fi network and printing its IP address.

Another way to find the NodeMCU IP address is by logging into your router. Most routers have a list of connected devices, and you can find the NodeMCU IP address by looking for its MAC address.

To find the MAC address of the NodeMCU, upload the following code to the board:

#include <ESP8266WiFi.h>

void setup() {
  Serial.begin(115200);
  Serial.println(WiFi.macAddress());
}

void loop() {
}

Open the serial monitor in the Arduino IDE and take note of the MAC address. Then, log into your router and look for a list of connected devices. You should be able to find the NodeMCU IP address by matching its MAC address to the list of connected devices.
