[External LED Blink][arduino] Connect external LED to Pin 12, then make it blink

1. Choose Blink code

File -> Examples -> 01. Basic -> Blink

2. Change the location of PIN from 13 to 12

/*

  Blink

  Turns on an LED on for one second, then off for one second, repeatedly.

 

  This example code is in the public domain.

 */

 

// Pin 13 has an LED connected on most Arduino boards.

// give it a name:

int led = 12;



// the setup routine runs once when you press reset:

void setup() {                

  // initialize the digital pin as an output.

  pinMode(led, OUTPUT);     

}



// the loop routine runs over and over again forever:

void loop() {

  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)

 // delay(1000);               // wait for a second

delay(200);               // wait for a second

  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW

 // delay(1000);               // wait for a second

delay(200);               // wait for a second

}
