Thank you for the explanation! I was wondering why the buzzer I was using was making an awfully sounding tone, turns out the kit provided two identical-looking buzzers - I was using the active one.

[@fun12222]

Thank you this helped me a lot

[@morteza7298]

ty sir, short, useful, well explained

[@patrickkantas9474]

Nice job man 👍.. btw sorry if i ask .. but is there any way how to make that buzzer wireless plus make the distance more longer like around 500 meters to 1km ? and when you press the button it will make the tone .. keep up the goodwork man .. big thanks

[@Science.Buddies]

Hi - there are a variety of wireless communication options for Arduino but unfortunately we do not have any of our own tutorials on them yet, so you would need to search online.

[@patrickkantas9474]

@@Science.Buddies ahh yes i also had that thought but is it more better to use some sort transmitter module or bluetooth/wifi ?

[@Science.Buddies]

You will need to look into the range of different wireless technologies. A kilometer is probably way too far for bluetooth or wifi. We can't really provide more help with this since we don't have our own tutorials, you may have more luck on the official Arduino forums.

@@Science.Buddies ahh alright man .. well thank you very much for the explanation bro .. wish the best for the channel

[@CraziMayur]

@@patrickkantas9474 I can help you. Take a lora module, configure it with arduino. It has a range of KM's

pls help guys

At the top there is a tab that says tools, click on it and then click on "port" just select the one that is available as an example: "COM5"

[@omvatisharma1161]

Can you please give me the code for both active and passive buzzer please

[@Science.Buddies]

Unfortunately RUclips doesn't like Arduino code formatting when we try to copy it into the video description, but you can just pause the video and transcribe the code into your Arduino IDE.

[@SocratesFil]

Thanks for the tutorial! Is it possible that a buzzer can in some way damage the output pin of the Arduino, perhaps drawing too much current or by backEMF of some kind? Is it completely safe to use them directly no matter which size of buzzer we deal with? Also the loudness of the sound is pretty low, is there any way to increase it?

[@Science.Buddies]

Hi - it would depend on the specs of your buzzer; in general these small buzzers are safe to connect directly to an Arduino pin. To be safe you could drive one with a transistor instead - look up our video on controlling DC motors, it would work the same way except with the buzzer instead of the motor.

@@Science.BuddiesThanks!

[@dandelion8533]

can they play sharps and flats

[@electricengine8407]

I'm pretty sure they can play almost any frequency within some range, so yes

[@millennial_bug]

3:00 they are pretty
