NodeMCU8266 Basic Project-Blink a LED

NodeMCU Basic Project-Blink a LED 

Today i show you how to Blink LED use nodeMcu8266

This Project Hardware Requirement

1. NodeMcu8266  
2. LEDm
3. Micro Usb cable
4. 200 ohm resistor

Software Requirment
Arduino IDE(version 1.6.4+)

 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
