  Circuit: Arduino Ek R4
  Sketch Description: This code reads the analog signal from a sound sensor.
 
  Read this for details on how Arduino compiles sketches distributed across multiple files.
  https://arduino.github.io/arduino-cli/1.0/sketch-build-process/#pre-processing
 
  All .ino files in the sketch folder are concatenated together, 
  starting with the file that matches the folder name followed by the others in alphabetical order. 
  The .cpp filename extension is then added to the resulting file.
