Click on this symbol you see the Page is open like as given below:

arduino window

Now this is your Arduino compiler and Ready to start with some code.

First program in Arduino

void setup() {
  // put your setup code here, to run once:
pinMode(16, OUTPUT);    //pin 16 represents D0 in Nodemcu 


void loop() {
  // put your main code here, to run repeatedly:
digitalWrite(16, HIGH);
digitalWrite(16, LOW);

After write the code on Arduino

>Go to tools option and select Board: “Generic Esp8266”

>Connect with NodeMcu

>Go to the tools option and select the COM port which is shown on the port.

>Click on the Right tick option

>Click on upload option then below screen is shown and give output.

Connect D0 and Gnd with the led bulb then the led light will glow.
