Student Blogging Challenge Week 5 – Music

For this week’s Student Blogging Challenge, the thing I chose to do is kind of a mix of Creating My Own Music by using technology, and discussing Music and The Law. I used an electronic part, called a piezo buzzer, and I made it play the national anthem of the United States, “The Star Spangled Banner”. I chose this song because it is a well-recognized tune in the US. On March 31, 1931, Congress declared the “Star-Spangled Banner” as the national anthem of the United States of America; therefore officially putting it under public domain, for anyone to use. There is some rules, though. At US sports games, the national anthem is preformed at the beginning of the game. You can’t take the audio from that specific performance. That is considered copyrighted.

Moving on to the electronics part of this project; if you take the black piezo buzzer, and you hook it up to an unregulated voltage of about 5 volts, it makes a high-pitched ear-piercing sound. That is why it is often used in alarms. I hooked up the buzzer to an arduino, which is a micro controller, similar to a mini-computer. I looked up the notes for the “Star Spangled Banner” and transcribed the notes into the code. I uploaded  the code via USB cable to my arduino, which took the commands I wrote, and played them out on the buzzer, forming a song. In this case, the song was the National Anthem. You can view the video above.
