   Objective:       
      This sketch focuses on wireless communication utilizing XBee Radios Series 1. 
      The system comprises two Arduino units, each equipped with an XBee shield and a radio module. 
      One Arduino is positioned outside your home or apartment, while the other is located indoors. 
      Upon pressing a button on the outdoor unit, the indoor board triggers the doorbell. 
      The previous code (18) is an integral component of this project.
      It was developed during the N.A.V.E TECH UNIR Samsung Eletrônica da Amazônia LTDA
      In Porto Velho - RO - Brazil, Course from November 2023 to April 2024. 
      The project was supervised by Professor Dr. Ciro José Egoavil Montero 
      (https://www.linkedin.com/in/ciro-j-egoavil-210b7a44/?originalSubdomain=br), 
      an Associate Professor III in Electrical Engineering at the Federal University of Rondônia (UNIR).

  Output:       This sketch is crafted to wirelessly push a button, resulting in ringing a tone and flashing the RGB LED.
