Creating Your 1st Project

LED blinking on NodeMCU

Lets first begin with a small program like our all time favorite LED blinking.

In this project we will turn on and turn off on board LED. This project will give you confirmation of basic working functionality of your module Like UART and LED.

Step 1 Open Arduino IDE.

Step 2 Copy the following program

/* 

NodeMCU example: Led blinking

*/

int LEDPin = 16;

void setup() {

              pinMode(LEDPin, OUTPUT);

  }

void loop() {

              digitalWrite(LEDPin, HIGH); delay(500);

              digitalWrite(LEDPin, LOW); delay(500);

  }
