1. This document describes three experiments conducted by Egi Agung Prayogi and Yoga Apriyansyah to control LEDs using a PIC microcontroller. 2. The first experiment used port A to light up LEDs in sequence on a single port. The second experiment used port C to light up LEDs in sequence and then reverse the sequence. 3. The third experiment used ports A and B simultaneously to light up LEDs in sequence across the two ports in a synchronized manner.
