8. LED Blink

How do you plan to solve it?

const int ledPin =6; // LED IS CONNECTED TO PIN 6


void setup() {
  // put your main code here, to run repeatedly:
pinMode(ledPin, OUTPUT); // SET THE LED PIN AS AN OUTPUT
}

void loop() {
  // put your main code here, to run repeatedly:
digitalWrite(ledPin, HIGH); // LED WILL TURN ON
delay(400); 
digitalWrite(ledPin, LOW); // LED WILL TURN OFF
delay(800);
}

Add video of the output (know more)
