This document contains code for using a Proteus simulation with a PIC microcontroller to blink an LED using different methods. It defines ports and pins as inputs and outputs, and uses pause commands to turn an LED on and off at set time intervals. It also includes code for initializing an LCD display using specific port pins and bits.
