Useful Piezo Buzzer sounds
Hi everyone,
I am completing my final project and I have a component that requires using the piezo buzzer for alerts/notifications and I noticed while going through some recent project proosals that there are some alarm type systems or projects that might need to incorporate sirens into the systems. While just having the buzzer go on and off is an option, it is not an optimal solution for alarm systems that serve to relay some type of info such as a siren to warn people or a basic reminder tone.
For my system, I chose to take this route after being Ric Rolled into an old projecthub post:
https://projecthub.arduino.cc/rowan07/rickroll-piezo-buzzer-b3d9fd
I also found an old github repo with some compiled songs that can be reviewed for anyone working with the buzzer:
https://github.com/robsoncouto/arduino-songs
Songs can also be easily compiled yourself by looking up the notes of the song and using circuit 2A of our SIK guide as a skeleton for the tune. Using public domain songs or compositions is a safe bet for a public project. However, using snipets of songs for educational purposes such as this is covered by fair use, but you would still want to cite the source of your songs. Additionally, if you choose to use a snipet and you upload your course videos to Youtube, it might be a good idea to upload it directly on landing instead or keep a copy of the video as it can be taken down automatically.

Hi Michael,
I appreciate you sharing your knowledge on piezo buzzer usage in alarm systems. I absolutely agree that more sophisticated systems can benefit from different tones or sirens to provide clearer notifications, even while basic on/off functionality is sufficient for basic alarms.
I appreciate you sending the link to the Rickroll project; it's a great way to show off the buzzer's potential! Another excellent resource for giving projects a musical flair is the GitHub repository containing compiled tunes.
Making your own music with circuit 2A from the SIK handbook is a good start. As you pointed out, it's safe to use music that are in the public domain, and crediting sources is important for educational pieces. It's wise to be mindful of any copyrighted content problems with sites like YouTube, so backing up your films with an alternate plan is a wise precaution.
Hey Michael,
This is a great project; I appreciate your efforts to enhance alert systems with the piezo buzzer. I completely agree that while a simple on and off buzzer is functional, adding sirens or melodies can improve the overall effectiveness of alarms and notifications.
Thanks for sharing the GitHub links. I’m excited to see how your final project turns out. Good luck!
Best,
Arham
Hey Michael,
This is a great project, and thank you very much for sharing it. I think it was a really good decision to go with differing sounds for an alarm system. I do agree that it can relay a lot more information that way, and make it much more useful for the end user.
I also am using a buzzer in my project, and providing the song resource that you did makes it a lot easier for me to generate my buzzer sounds. So, thank you very much for providing the resource!
Thanks for sharing these valuable resources on using piezo buzzers for more dynamic alarm systems. The links to the Rickroll project and the GitHub repository with compiled songs are fantastic additions! I agree that varying the alarm sounds can greatly enhance the system's utility by providing distinct notifications for different alerts.
I'm curious, have you encountered any challenges in synchronizing the buzzer tones with the specific events in your project?
