Task 13 - One LED mostly on the other LED has a slight flash.

int ledPin = 13; // LED connected to digital pin 13
int redLedPin = 12; // LED connected to digital pin 12
int del =100;


// The setup() method runs once, when the sketch starts


void setup() {
// initialize the digital pin as an output:
pinMode(ledPin, OUTPUT);
pinMode(redLedPin, OUTPUT);
}


// the loop() method runs over and over again,
// as long as the Arduino has power


void loop()
{

digitalWrite(ledPin, HIGH);
digitalWrite(redLedPin, LOW);
delay(del);
digitalWrite(ledPin, HIGH);
digitalWrite(redLedPin, LOW);
delay(del);
digitalWrite(ledPin, HIGH);
digitalWrite(redLedPin, LOW);
delay(del);
digitalWrite(ledPin, HIGH);
digitalWrite(redLedPin, LOW);
delay(del);
digitalWrite(ledPin, HIGH);
digitalWrite(redLedPin, LOW);
delay(del);
digitalWrite(ledPin, LOW);
digitalWrite(redLedPin, HIGH);
