Hello, I read with great interest his project and decided to realize it, but I have a problem in compiling the Sketch with Arduino. I'm getting errors in compiling the type: "previous definition of 'class MLX90615' " . Arduino 1.8.14 use. Kindly you could have the full file already filled in? Or a guide to proper compilation? I apologize for the language used.
An early thank you to those who can help me solve this problem.
