Let’s Begin!

To install the required files to program the NodeMCU using the Arduino IDE, follow the steps below.

Step 1: Download Arduino IDE from the official Arduino website: Download

Step 2: Install the software and connect the NodeMCU board to your computer using the micro USB cable.

Step 3: Start Arduino IDE and navigate to File -> Preferences.

Step 4: Copy the link below and paste it in the Additional Boards Manager URLs tab.


Click OK to close the preferences window.

Step 5: Navigate to Tools -> Board -> Boards Manager.

Step 6: In the Boards Manager window, type esp8266 by ESP8266 Community. Select it and install it onto the Arduino IDE

Step 7: Navigate back to Tools -> Board, find and select NodeMCU 1.0 (ESP-12E module) board.

Step 8: Go to Tools -> Port and choose the port that corresponds to your NodeMCU.

You can find this port number by opening the Device Manager from your computer’s Start Menu. From the list, look for the COM port number of USB-UART bridge or something similar.

In a few computers, the UART port will not be present and hence cannot be detected, for that you have to download a USB to UART port converter from here.

Now that your installation process is completed, let us begin programming the NodeMCU using the Arduino IDE.
