How To Use: Tone Function - Arduino Playing The James Bond Theme

On this tutorial you will see how to use the tone function to play monophonic music.

Materials List: 

1 x Arduino Uno R3

1 x Breadboard

1 x Speaker 8 Ω / 0,25 W

1 x Rotary Potentiometer 10 KΩ

1 x Capacitor 100μF / 25 V

Jumpers

How it works:

The syntax of tone function is:

tone (pin, frequency, duration);

The parameters are:

 

pin: the pin on which to generate the tone

frequency: the frequency of the tone in hertz - unsigned int

duration: the duration of the tone in milliseconds (optional) - unsigned long

The tone function generates a square wave of the specified frequency on a pin during the time of duration field (optional).

Each musical note is determined by a frequency and you can see on table below the frequencies:

Based on this table and pentagram above the archive pitches.h (of toneMelody example) was created.

The array melody[] is used to store the notes, using names to correspond to the note and frequency.

For example, the frequency of note A4 (A for "La" and 4 for the 4th octave) is 440 Hz in the array it will be called NOTE_A4.

The musical score represents the notes and the duration by symbols on the pentagram.

Below you see clef-G and clef-F.

The duration is determined by the following symbols:

In array noteDurations[], the durations were represented by numbers.See table below.

Symbol 

Value in array

whole note

1

half note

2

quarter note

4

eighth note

8

sixteenth note

16

           thirty-second note

32

            sixty-fourth note

64 

 

The potentiometer was used to control volume and the capacitor as coupling.

Below you see the circuit on Fritzing.

 

The Sketch:

Verify circuit, and upload Sketch to Arduino:

    int duration = pace/noteDurations[Note];//Adjust duration with the pace of music
    tone(8, melody[Note],duration); //Play note

// to distinguish the notes, set a minimum time between them.
    delay(duration*1.2);

Let's listen James Bond!!!
