GETTING STARTED WITH NODE-MCU ESP8266 WIFI MODULE

FOLLOW THESE STEPS TO WRITE ARDUINO SKETCH FOR NODE MCU ESP8266 

 IOT PLATFORM

STEP 1:- 

Boards manager link: https://arduino.esp8266.com/stable/package_esp8266com_index.json

OPEN ARDUINO-IDE SOFTWARE => FILES => PREFERENCES => PASTE THE LINK ON 

Additional Boards Manager URL's

STEP 1:- 

NOW GOTO Tools  => Board => Boards Manager

open "boards Manager" => type "esp8266 community" => select version and click on "install"

after completion of the installation, it will look like this

STEP 3:- 

******installed successfully******

NOW LET'S CHECK HOW THIS IS WORKING 

NOW GOTO Tools  => Board => Esp8266 Boards => select "NodeMCU 0.9(ESP-12 MODULE)" 

NOW GOTO "FILES"  => "EXAMPLES" => "ESP8266" => "BLINK"

JUST UPLOAD BASIC "BLINKING SKETCH"

void setup() {

  pinMode(LED_BUILTIN, OUTPUT);     // Initialize the LED_BUILTIN pin as an output

}

// the loop function runs over and over again forever

void loop() {

  digitalWrite(LED_BUILTIN, LOW);   // Turn the LED on (Note that LOW is the voltage level

  // but actually the LED is on; this is because

  // it is active low on the ESP-01)

  delay(1000);                      // Wait for a second

  digitalWrite(LED_BUILTIN, HIGH);  // Turn the LED off by making the voltage HIGH

  delay(2000);                      // Wait for two seconds (to demonstrate the active low LED)

}
