Section 2: Hardware and Software Requirements

Before setting up Blynk 2.0 with NodeMCU ESP8266, ensure you have the following:

1. NodeMCU ESP8266 board

• 2. USB cable for NodeMCU
• 
  
• 3. Computer with Arduino IDE installed
• 
  
• 4. Stable internet connection
• 
  
• 5. Smartphone (Android or iOS)

Section 3: Installing Blynk Library

To start, you need to install the Blynk library in your Arduino IDE.

Open the Arduino IDE and go to "Sketch" -> "Include Library" -> "Manage Libraries." Search for "Blynk" and install the latest version of the Blynk library.

Section 4: Creating a Blynk 2.0 Account

To use Blynk, you need to create an account. Visit the Blynk website (blynk.io) and sign up for a new account. Once registered, log in to your Blynk account.

Section 5: Creating a New Project

After logging in, click on the "Create New Project" button. Give your project a name and select the hardware model as "NodeMCU." Choose the connection type as "Wi-Fi."

Section 6: Setting up the NodeMCU ESP8266

Connect your NodeMCU to your computer using the USB cable. In the Arduino IDE, go to "Tools" -> "Board" and select "NodeMCU 1.0 (ESP-12E Module)" as the board. Make sure the correct port is selected under "Tools" -> "Port."

Section 7: Programming the NodeMCU ESP8266

Now, it's time to program the NodeMCU ESP8266. In the Arduino IDE, go to "File" -> "Examples" -> "Blynk" -> "ESP8266" -> "ESP8266_Standalone." This example code provides a basic template for connecting your NodeMCU to Blynk. Replace the Wi-Fi credentials and the Blynk auth token with your own.

Section 8: Testing the Setup

Upload the code to the NodeMCU by clicking on the "Upload" button in the Arduino IDE. Once the upload is complete, open the Serial Monitor to view the NodeMCU's IP address.
