LED Blinking using Arduino Circuit and Programming

We will create a program for LED light blinking using Arduino Uno, first We'll discuss about LED Light Blinking of programming and then we'll put/insert LED light to the Arduino Uno Circuit in last we'll see LED light of blinking of OUTPUT.

The Code:

int ledpin = 13;

void setup() {
// put your setup code here, to run once:

pinMode(ledpin , OUTPUT);

}

void loop() {
// put your main code here, to run repeatedly:

digitalWrite( ledpin, HIGH);
delay(1000);

digitalWrite( ledpin, LOW);
delay(1000);

}

OR

If you directly want to use the pin number instead of variables

void setup() {
// put your setup code here, to run once:

pinMode(13 , OUTPUT);

}

void loop() {
// put your main code here, to run repeatedly:

digitalWrite( 13, HIGH);
delay(1000);

digitalWrite( 13, LOW);
delay(1000);

}
