![]() The note and its corresponding duration is what is there in melody and noteDurations respectively. Higher value gives longer duration notes. Here 8 = quarter note, 4 = 8th note, etc. Then I wrote noteDurations according to the length of each music note. I wrote down the musical notes of this song first and then wrote the melody array with that. I found out the notes of this song with my guitar. The first array contains the notes and the second array contains its corresponding durations. It is similar to how ringtones were written in old Nokia cell phones. 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, weâll 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, âtone( )â.
