Story

Many people asked me to programme NodeMCU with Arduino IDE so I decided to write this guide.

Installing the NodeMCU Support for the Arduino

First open the Arduino IDE

Go to files and click on the preference in the Arduino IDE

Paste below URL in the Additional boards Manager

http://arduino.esp8266.com/stable/package_esp8266com_index.json

click OK, It will close the preference Tab.

Now, Go to Tools and board, and then select board Manager

Navigate to ESP8266 by ESP8266 community and install the software.

Once all the above process is completed we are ready to program our NodeMCU with Arduino IDE.

Lets Test It With Blink Programme

Now, go to Tools, board and select the type of NodeMCU you have

Then select the correct COM port to upload the program on your NodeMCU

Now Copy Paste the below programme and upload it.

If you did everything correctly then, your led should blink continuously.

If you have any query or issue please comment below.

Blink Inbuilt LED of NODEMCU

void setup() {   
  // initialize inbuilt LED pin as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on by making the pin 13 HIGH
  delay(500);              // wait for a 0.5 second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the pin 13 LOW
  delay(500);              // wait for a 0.5 second
}
