   Objective:       
      In this project we will be crafting Version 1 of a non-contact thermometer.
      This example reads from the MLX90614 and prints out ambient and object temperatures 
      every half-second or so. Open the serial monitor and set the baud rate to 9600.
      An LED can be attached to pin 8 to monitor for any read errors.
      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).
