Product Showcase: Qwiic Buzzer

[@delawarepilot]

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

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

[@robreynolds6546]

Spot on, and thanks for that bit of musical trivia about the song's usage, too!

[@MarkSidell]

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

[@atiluluyuce]

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 👏

[@ChristopherBrandsdal]

Great video! Very fun to see the ideas behind.

[@davidwilliams1060]

Thanks, good information. Really liked the dancer.

[@jimbarchuk]

I see a recurring cameo part.

[@happyhippo4664]

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.😀

[@PaulNaybour]

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

[@MMuraseofSandvich]

Pete himself!😊

PNP resistor not needed. GPIO sinks just base current.

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

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.

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...

[@happyhippo4664]

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.

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

[@planker]

I caught a buzz.

[@robreynolds6546]

I see what you did there

[@PriyankBolia]

Why not a programmable resistor?

[@kevy1yt]

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

[@rgsparber1]

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.

[@rgsparber1]

Oops, I was wrong about the PNP resistor. You do need it. If NPN you don’t but would lose about 0.4v over what you have.
