This file contains all the pitch values for typical notes. The code below uses an extra file, pitches.h. Pin: the pin on which to generate the toneįrequency: the frequency of the tone in hertz - unsigned intĭuration: the duration of the tone in milliseconds (optional) - unsigned long The Arduino pin can be connected to a piezo buzzer or other speakers to play the tones. ![]() Otherwise, the wave continues until a call to noTone (). ![]() It g enerates a square wave of the specified frequency (and 50% duty cycle) on a pin. ![]() The program creates tones with a function, ‘tone( )’.
