Why?
I created the library because there was no way to play 8-bit classical music while your main sketch was running. Additionally, playing other people's music files was difficult and disorganized.
I want to play more than one note at the same time. After much research, I acquired this ability using Bhagman's Tone library. Unfortunately, the number of notes that can be played at the same time depends on the number of timers your array has (cannot use Timer0 since millis() uses it). The Arduino Uno can therefore play up to 2 notes at the same time.
How does it work?
To learn how to read and create your own music, learn RTTL in my library's $ReadMe file
RTTL is an extremely easy to understand language for musicians and beginners
Benefits
Play more than one note at the same time
Run other things like serial monitor in the background
Play music backwards and forwards
Pause/play music
Skip to specific sections of the song
Choose a new song
more to come :D
Legend of Zelda
arduino
A demo of my MusicWithoutDelay library. It plays the Legend of Zelda and allows the user to pause/play, skip and reverse the song at any time. Better yet, since it doesn't use delay(), you can easily add more code to it and make it do other cool things, like read the serial monitor or display on an Oled.
