I got this arduino flora for my birthday and wanted to program it to sing happy birthday.
What it does
It is essentially a hardware hack using the Adafruit Circuit Playground FLORA board sewn onto a purple marshmallow plushy that plays a special version of happy birthday when the program is run.
How I built it
I programmed the tune according to the note frequencies. I used the Arduino IDE to upload my program to my FLORA board. Then, I used string to sew my FLORA board onto my marshmallow plushy. I chose to make a marshmallow because of the cylindrical shape that matches the board.
Challenges I ran into
Adjusting the notes and pitches of the song was a challenge because many notes were either sharp or flat. I had a hard time adjusting the time in milliseconds since some notes needed to be longer than others.
Accomplishments that I'm proud of
I was able to make a complete song out of my Adafruit FLORA board that is not only something I have never tried before, but is also my first hardware hack!
What I learned
I learned how to program notes onto a software and upload it onto hardware and that programming can be easily exported to real hardware.
What's next for Birthday Marshmallow
I have LED lights sewn on with a wire, but does not light up yet. Blinking lights are next for my birthday marshmallow.
