How do you introduce musical notes for the song?

The command beep(note,duration) is used where note defines the frequency and duration sets the length.

What happens visually when a note sounds?

A red or green LED turns on alternately every time a note is played.

Can this project play songs automatically at a set time?

Yes, a timer feature allows the song to be programmed to play at a specific moment without immediate interaction.

Which songs are pre-programmed in the system?

The system includes Happy Birthday, La Cucaracha, The Rains of Castamere, and Star Wars.

How does the user select which song to play?

Users choose from a web page generated by the Arduino server using specific links for each track.

What libraries are required to run the code?

The code requires WiFi101, WiFiClient, WiFiServer, WiFiSSLClient, and SPI libraries.

How are silence periods handled in the music sequence?

The delay function is used to create silences between musical notes.

Can new songs be created if you know the frequencies?

Yes, any other song can be played if the music sheets and note frequencies are known.

Summary of Singing Arduino

This project enables an Arduino MKR1000 to surprise users by playing programmed songs like "Happy Birthday" or "Star Wars" via a web interface. It features automatic timer capabilities and visual feedback where LEDs alternate colors with each note. Users can select specific tracks or play them sequentially through a simple browser-based menu, making it an ideal DIY musical gift that requires only basic knowledge of frequencies to create new melodies.

Parts used in the Singing Arduino Project:

Buzzer
5 mm Red LED
5 mm Green LED
Resistor 330 ohm

Story

Would you like to surprise someone with a song? You pretend you forgot a birthday and suddenly the song starts playing while you give the present. Arduino can help you with this incredible gift. It can be either Happy Birthday, Star Wars or ABBA. You only introduce the musical notes (pretty easy nowadays, even if you don’t know sol-fa), a timer, and voilà: the perfect gift.

This project consists of a web page where you choose the song you want to play among those that are already programmed with Arduino/Genuino MKR1000.

This program has multiple options: songs can be played by choosing one of those programmed in the web page, playing all of them in a row or setting a timer to play a song automatically.

To make it more versatile, a time is added, so that the song can be played without the need of doing it on the spot, but programming the Arduino for it to play in a certain moment.

Moreover, as every note sounds, a led turns on, alternating red and green colours.

Knowing the frequencies of every note, showed below in the image, and having the music sheets, songs can be created.

Frequencies

Music sheets

Some of the programmed songs are Happy Birthday, La Cucaracha, The Rains of Castamere and Star Wars, but any other song can be played.

The command to introduce one note is beep(note,duration) where note is the name of the note (Do, Re, Mi, etc., already defined with their frequencies) and duration means how long the note is (minim, crotchet, quaver, etc.), and delay is used for the silences.
