PIC16F-7-INTERRUPT-Header&Configuration

/*
* File: main.c
* Author: Marwen Maghrebi
* 
* Description: 
* This code demonstrates interrupt-driven ADC reading and UART communication on a PIC microcontroller.
* It blinks LEDs, reads analog voltage from a potentiometer, and sends the voltage readings via UART.
* Additionally, it handles an external button interrupt to trigger an LED blink and UART message.
