Important safety warning
This project will create a loud, annoying, high-pitched sound. We strongly advise the use of hearing protection (earmuffs or earplugs) when working in close proximity to this project.
Parts & wiring
Do you know what’s definitely not music? What you’re about to build. In fact, it’s probably as far from music as you can get. It’s so annoying that we even had problems testing the program. It’s just that bad.
What you’ll need for this project
To build this project, you will be using the following components:
UNO R3 Board & USB Cable
Piezo Buzzer
How to connect the parts
To wire up this project, you’ll need your UNO R3 boarding buzzer. To connect your buzzer, slide its pins into the Arduino board as shown – the positive leg should go in PIN 11 and the negative leg should go in GND.
Hover over the PLUS signs for extra tips
This is the positive leg of the buzzer. It will have a ‘+’ sign on top of it and will also be longer than the other leg.
Don’t forget to plug the board into your computer with the included USB cable.
The final program
Here’s the code we’ll be using to program this invention.
int buzzer = 11;
void setup() {
// put your setup code here, to run once:
pinMode(buzzer, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
digitalWrite(buzzer, random(2));
delay(1);
}
