First you have to need board selection on Ardunio IDE
Tool>> Board>> NodeMcu0.9 or1
Then you have to need Port Selection
Tool>> Port (select your port no)

int pin =3;
void setup() {
// initialize GPIO 3 as an output.
pinMode(pin, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(pin, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(pin, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
Now you are ready to play one this connection
