Product Showcase: Qwiic Buzzer

The SparkFun Qwiic Buzzer adds simple beeps and buzzes to your projects via I2C Make some noises to alert you when something interesting (or urgent) happens. Simply connect a Qwiic cable and load up some pre-written code to an Arduino to start making noises!

I’m impressed by the clarity of his circuit drawing skills.

A buzzer? I wasn’t expecting much from this week’s video. Delighted to be wrong.

11:26 Bugler's Holiday. I only knew this one because Japanese schools sometimes use this for track and field day.

I'm very impressed with how much you enjoy what you do. There is no possibility that the work done with this mindset will be anything other than magnificent. Congratulations 👏

Great video! Very fun to see the ideas behind.

Thanks, good information. Really liked the dancer.

You did your job well. I was motivated to buy some of the buzzers and other stuff as well, including a xrp kit. I think I got the last ones - you need to make more.😀

If I wanted to transcribe music in 4/4 time that has quarter note triplets. To keep everything integers, would I have to have durations of quarter note = 12, eigth note = 6, sixteenth note = 3, and triplet quarterr note = 8, then play it back 12 times faster?

EDIT: Or, I see in the library that it goes the other way around. Where quarter notes are 4, eighth notes are 8, sixteenth notes are 16 - so triplet quarter notes would be 6? So I guess I wouldn't have to play it back faster.

Is there a tutorial that describes the fastest and most efficient way to encode a melody for this use? I was only able to get 3 buzzers. So I can take a bass note and two treble notes. I understand I can play them at the same time to form chords. I saw that library example on melody and the note variables have long names.

1in by 1 in is 1 Sq in. 25.4 mm by 25.4 mm is not 25.4mm sq 645.16mm sq

I love the new at the bench format, especially the hardware engineer who can’t remember the code.

Why not just change the duty cycle to modulate amplitude instead of several gpio lines & a few transistors and resistors?

[rd_Millennium_Engineering]

This is a great video for an electronics neophyte like me. Would anyone know if this could also be programmed for several tones over a few seconds autonomously? Oh wait; I have to watch all the way through before commenting, heh heh heh. Thanks Rob and Company for another great product to add to my shopping cart...

PNP resistor not needed. GPIO sinks just base current.

[logictechs]

Maybe next version use a digital resistor to have a wider volume control range?🤓

[rgsparber]

You compared 20 mA, average current, to peak of 50 mA. My guess is your peak current with direct drive is much less than peak with PNP. Look at GPIO voltage direct drive and I bet it is much less than 5v.
