I combined this exact setup with a battery and a PIR sensor to make a portable motion sensor alarm in a small cardboard box. Very fun for the kids to play with.
I found some guy who calculated 300mA, so a 220 resistor would be enough to keep it 20mA. maybe it wasn´t from a pin but from the supply (just in case, I would put it)
Hi Chris, I just found your channel. I'm a complete beginner when it comes to Raspberry Pi's, but I have a question: can the pico store source code on the controller itself, so it can run autonomously? (after you hook it up to some batteries of course). I'd like to build something that beeps every X seconds, but I don't want to have to plug it into a computer in order to work.
Hello Koenhd718, Yes you can. I think these two videos will help you out. HOW TO MAKE THE RPI PICO AUTORUN A PROGRAM ua-cam.com/video/2fLME6EresI/v-deo.html INTRO TO BATTERY POWER FOR THE PICO ua-cam.com/video/UlKjjkLG69s/v-deo.html Welcome to our community! Cheers Chris
Just trying to figure out why im getting no sound? Set up and code are the same. I thought it was my buzzer, but I tried a different code and all was well... any thoughts?
Hmm, this thing is pretty simple, not much to go wrong. Be certain to remove the sticker covering the hole, sounds cannot be heard with it covered. You can also test it by applying 3.3V to the PLUS leg and OV to the other leg and it should make sound. Next would be, can you hear at that frequency? I have a LOT of trouble at higher frequencies, but that buzzer was easy for me to hear.
Just found your channel and I love it already! Your authentic and simple video format is awesome! Keep up the great work.
Thank you very much for the kind word and I am happy you found the channel!
Cheers!

Awesome sounding project! I LOVE it.
Cheers,

Great tutorial
Good morning chandikawarnakulasooriya1923
THANK YOU and I am glad you liked it.
Cheers!

looks useful but how much current does it draw from the output pin?
There was no specification provided.
Cheers!

Did you figure it out? I have the same problem :/.
Awesome, love this! Also, this was 2700Hz 😛
Hi RETARDIRANY,
Glad you liked it!

I like the annoying warble. I'm going to foist it on some unsuspecting factory workers.
LOL! Sounds like fun in the making!
Cheers!
