   Objective:       
      This sketch is to upload to Arduino paired with nRF24L Radio. SEE Project #28.
      This is the most basic and straightforward test ever conducted for dealing with the nRF24L Radio.
      The receiver acknowledges the transmitter.

      This is a component of my study on nRF24L0 radios.
      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).

   Software:    Arduino IDE 2.2.1
                  
   Connections: 
               Arduino - Radio SPI - Wire Color
                   7   -  CE       - Black
                   8   -  CSN      - White
                  13   -  SCK      - Orange
                  11   -  MOSI     - Yellow
                  12   -  MISO     - Blue
                   3   -  IRQ      - Red

   output:      The radio receives an integer that increments by one.
