      In Porto Velho - RO - Brazil, Course from November 2023 to April 2024. 
      The project was supervised by Professor Dr. Ciro José Egoavil Montero

   Objective:          
      This implementation relying on interrupts offers distinct advantages over the previous code(#37), 
      especially in scenarios involving time-sensitive events, such as motion detection. 
      Interrupts empower the microcontroller to swiftly react to changes in the sensor state without 
      the necessity for continuous monitoring within the primary program loop, 
      distinguishing it from conventional polling techniques (#37).

      Link: https://medium.com/jungletronics/pir-motion-sensing-led-display-6192f403c7db
   
   Objective:           
      This first code utilizes a polling approach, where the detection of motion relies on repeatedly checking 
      the sensor state within a loop and waiting for changes. This code employs a PIR sensor to identify motion 
      and adjusts an LED accordingly. Messages indicating the initiation and cessation of motion are printed to 
      the serial monitor. The pirState variable is employed to track the motion detection state, 
      preventing the generation of redundant messages.
