NodeMCU is an open-source firmware and development board that is based on the ESP8266 Wi-Fi module. It is a popular platform for Internet of Things (IoT) projects due to its low cost, ease of use, and versatility. In this article, we will discuss how to set up NodeMCU on Arduino IDE.
Step 1: Install Arduino IDE
The first step is to install the Arduino IDE on your computer. You can download the latest version of Arduino IDE from the official website https://www.arduino.cc/en/software. Choose the appropriate version for your operating system and follow the installation instructions.
Step 2: Install ESP8266 Board Manager
After installing the Arduino IDE, you need to install the ESP8266 board manager. This is necessary to add the support for NodeMCU to the Arduino IDE.
To do this, open the Arduino IDE and go to File > Preferences. In the Additional Boards Manager URLs field, paste the following URL:
http://arduino.esp8266.com/stable/package_esp8266com_index.json
Click OK and go to Tools > Board > Boards Manager. In the search box, type “esp8266” and select the “esp8266” board by ESP8266 Community. Click Install.
Step 3: Select the NodeMCU Board
After the installation of the ESP8266 board manager is complete, go to Tools > Board and select “NodeMCU 1.0 (ESP-12E Module)”.
Step 4: Select the Port
Next, you need to select the port to which the NodeMCU is connected. Go to Tools > Port and select the appropriate port.
Step 5: Upload Your Sketch
Now, you are ready to upload your sketch to the NodeMCU. In the Arduino IDE, click on File > New to create a new sketch. Write your code and then click on the Upload button to upload the sketch to the NodeMCU.
Step 6: Verify Upload
Once the upload is complete, you can verify that the sketch has been successfully uploaded by opening the Serial Monitor. Go to Tools > Serial Monitor and set the baud rate to 115200. If everything is working properly, you should see the output from your sketch in the Serial Monitor.
