There are two ways you can connect LEDs to controller port.
1. Active High Logic
2. Active Low Logic.
1. Active high logic means LED will be on when port pin is 1 and LED will be off when pin is 0. In this type of arrangement, LED is driver from port pin of controller if port pin does not have enough current then a pullup is used on.
