Measure the main frequency of analog captured signal connected to an Arduino and check for noise and mute.
Detects frequency from 38 Hz to 9612 Hz and works even on an ATTiny85 with 1 MHz up to 4806 Hz. Signal can be delivered e.g. by a microphone. New: Renamed printSignalValuesForArduinoPlotter() to printInputSignalValuesForArduinoPlotter() etc.
