PIC16F-9-TIMER-Configuration&Initialization

/** 
 * File: main.c
 * Author: Marwen Maghrebi
 * Description: This project demonstrates how to control the brightness and color of an RGB LED using PWM 
 * (Pulse Width Modulation) on the PIC16F877A microcontroller. The microcontroller is set up to produce PWM signals 
 * that control the RGB LED's colors through different duty cycles, creating a smooth fading effect.
