How I made melody and noteDurations of this song: If you take a look at the program, you can find two int arrays: melody and noteDurations. You may find it useful whenever you want to make musical notes for your Arduino speaker. This note table was originally written by Brett Hagman, on whose work the tone() command was based. So instead of writing the frequency in the tone( ) function, we’ll just have to write the name of the note. 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( )’.
