Very new beginner to Arduino here.
I am trying to make 3 LEDs blink in sequence, but all the tutorials I have found online are using wires that go to a separate board (a bread board?) and the LEDs have been inserted to that instead.
I want to have all 3 LEDs using the pins on the actual Arduino. I have worked out how to do one (Using Ground and pin 13) I just don't know how to make more output pins for the other ones.
Any help would be greatly appreciated! Thank you.
