Do you need to make some noise with Arduino? Maybe a simple tone for an alarm, maybe a beep to alert you when a specific input threshold is met, or maybe to play the Super Mario Brothers soundtrack to entertain your juvenile mind (it’s OK, we are all there too).
Whatever your audible need, you will likely find the easiest, quickest and possibly the cheapest way to make some noise is using the tone() function and piezo speaker with your Arduino.
###This is exactly what you will learn in this lesson:
1. A quick intro to piezo speakers (aka piezo buzzers)
2. How to set up a simple piezo speaker circuit
3. The basics and more of using the tone() function
4. The limits you should know when using tone()
###Hardware You Will Need:
* Arduino board, I am using an Arduino Uno [1]
* Solderless breadboard [1]
* Jumper wire [2]
* Piezo speaker (aka piezo buzzer) [1]
* At least 12 cm dental floss, with a thick wax coating (mint flavored works best) [1]
###A quick intro to piezo speakers (aka piezo buzzers)
Ahh noise….
Birds make it, kids make it - it can be music to our ears or pure torture.
We are going to use a piezo buzzer to make some noise with Arduino.
A piezo buzzer is pretty sweet. It’s not like a regular speaker that you might think of. It uses a material that’s _piezoelectric_, it actually changes shape when you apply electricity to it. By adhering a piezo-electric disc to a thin metal plate and then applying electricity, we can bend the metal back and forth, which in turn creates noise.
The faster you bend the material, the higher the pitch of the noise that’s produced. This rate is called frequency. Again, *the higher the frequency, the higher the pitch of the noise we hear*.
So basically, by shocking the plate over and over really fast, we can make noise. I don’t know who comes up with this stuff, but they’re friggin’ mean.
Now let’s set up this circuit.
###How to set up a simple piezo speaker circuit using Arduino
It’s painfully easy to set up a simple piezo speaker circuit with an Arduino.
1. Place the piezo buzzer into the breadboard so that the two leads are on two separate rows.
2. Using jumper wires, connect the positive lead to Arduino digital pin 8 and the other lead to any Arduino ground pin. The case of the buzzer may have a positive sign (+) on it to indicate the positive lead (if not, then the red wire usually indicates the positive lead).
That’s it.
Let’s go ahead and jump into the Arduino sketch.
###The basics and more of using the tone() function
The tone() function works with two arguments, but can take up to three arguments. Let’s address the two required items first:
tone( pin number, frequency in hertz);
1. The pin number that you will use on the Arduino.
2. The frequency specified in hertz. Hertz are cycles per second.
The frequency is an unsigned integer and can take a value up to 65,535 - but if you are trying to make tones for the human ear, then values between 2,000 and 5,000 are where our ears are most tuned.
As an experiment, try changing the second argument in tone() to 100, 1000, 10000, 650000 and listen to the effect it has on the audio signal.

i bought larger piezo speaker, is it posible to send pin where tone out to step up module, so my piezo got louder...?
you all prolly dont care but does anybody know of a method to log back into an Instagram account..?
I stupidly forgot the login password. I would love any tips you can give me.
My left ear really enjoyed this...but the right one feel left out.
lol!
Dude you don't know how much this has helped me
+Tom Budin Glad it help!
Nice and clear tutorial. Thanks for this.
So nice! Thank you for your calm and thorough walkthrough. Great work ! Really appreciated
+Søren Storm btw - I did the dental floss thing. Really cleaned my teeths
you are a fantastic teacher, Awesomely clear...nice work!
Thank you for this video. It was really helpful and informative.
Thank you very much for sharing your knowledge!
My left ear enjoyed the musical tone
my left ear enjoyed this video very much
great presentation skills u got there!
This is exactly what I needed for a diy sound wave generator with a buzzer for a school project!
Also, even though it's mentioned in every comment bellow, great tutorial.
Thank you so much! I am glad it helped!
my left ear enjoyed it !
it's piezo not peizo, great tutorial btw, actually all your tutorials are great i watched them all and learned a lot.
3:14
Nice job!
Your video helped me a lot, thanks Buddy !
Glad it helped!!
I only have sound in the left channel on this video, is that done on purpose?
***** i now hear that if I turn the volume way up there is son on the right channel too, but it is very low volume
***** That was a production error on my end. I just got some new equipment that I am still figuring out. Shouldn't happen again - but thanks so much for bringing it to my attention!
thaks a lot :) it is great explaining
Great ...Thank You.
good explination, thanks!
Thanks for watching! I hope it helped some.
you had me with dive bar.
I liked the inclusion of limitations, and the annotation to explore erroneous sounds. perhaps a video response is in order.
thanks man
Amazing knowledge sir...
great material! thanks for showing this! Appreciate your research on all specific details of the tone fn
Great video..
Thanks!
Thx
4:23 "One Hert" ... lmao
well..I used passive buzzer but I don't if it's better than peizo buzzer.
Thank u very much, u helped me :)
Thank you
I hope it helped!
Great Thank you, please upload a video how to create a sound like car horn sound.
Could this be used for anti dog barking at 20KHz . What speaker/buzzer would be best for this ? What sound in db can it create
New subscriber♥️
Thanks for subbing!
Is there any tool out there which coverts an audio sample to an array of frequency-duration pairs for use with the tone function?
I've tried creating a pushbutton synth using the tone function, but the tone only seemed to play after releasing the pushbutton. Is there any way around this?
Do this:
tone(peizoPin, 3000);
delay(100);
noTone(); [or what about tone(peizoPin, 0);] immediately turn off the tone
delay(1000); [and now your tone doesn't overlap into the delay]
So write a class/method or function called beeper(int pinout, int hz, int Tdelay);
{
tone(pinout, hz);
delay(Tdelay);
noTone();
}
- cheers -
Now you can oscillate the oscillator so to speak without time corrections having
to be calculated inline every single time you make the call to tone.
Great video. The video voiceover is only on the left speaker.
*Best tutorial ever on the earth!!*
BTW can u make the Chinese Cuckoo clock tone using Arduino?? 🙂 Because of how to make that "vintage Bell" sound and also the birds sound at the same time, I'm just confused, I mean the coding.. .🙂 I mean how I will know what frequency tone will be on for what seconds to generate the cuckoo sound?? that is my question!!
Is their any way to have more than one speaker playing at the same time when your using ultrasonic speakers. I think I have seen someone do something similar to that before, but I am not sure what steps they did to get to that result.
Nice! ..
yurit Sukoz Thanks for watching!
nice
Does tone() work with regular "PC Speaker" .5w 8 Ohm speakers too? I guess it would be much quieter if it does...
Hi, could I use this for a bell sound with a 8ohm speaker?
I need help please :(( I am trying this for my project. I already made a sketch for the piezo buzzer's sound but when I tried it with a 9V Battery, the patter doesn't work? Is there a way for it to work in 9V Batteries? Please I need help :((
Sir can you help me in choosing resistors in circuit how to determine the ohms
Dude im a german and i Unterstand it, pretty giod
Anyway that I could get a bell sound like a railroad crossing sound ?
Hi!
How can I make Arduino play a music note or a song?
ok but how do we make it useful? say i want to use keypad and have it emit a tone every time a key is pressed and not have the code interfere with the rest of the code?
i am trying to make a garage door keypad with a keypad and relay and 2 LED's
i want the pad to emit a tone every time a key is pressed and another tone if the code is wrong and yet another tone if it is wrong
are these buzzers waterproof?
I want to use tham as mist maker by emitting ultrasonic sound.
I'm following along your tutorials and I noticed that resistors were used in different ways. Sometimes voltage passing through, sometimes one end goes to the GND and sometimes one end is interrupting the flow and the other end goes to the GND. Is there any guideline/tutorial on how to use resistors in what kind of situation? Thanks.
Nice observation.
it depends on what you are trying to accomplish.
if you are using the resistor to limit current it will be in series with the load (like an led).
otherwise it may be used as a pull up resistor to tie a pin to positive voltage or a pull down to tie a pin to ground ( used with buttons and switches to avoid pin float irregularities ).
you should invest more in studying use of resistors. there are many clever tricks you will learn.
"An easy way to make noise in the left audio channel when rendering a tutorial video" ;) Pro-Tip: assuming you already send your windows audio through a pro mixer like VoiceMeeter Potato -- tell the audio stream it's Mono, and it'll come out of both ears. Cheers!
im using tone() without using pin 3 and 11, yet it still creates artifacts (the buzzer makes noise while not activated with tone(), and my led matrix's lights are dimmer and flicker at times). how to fix???
أهلا وسهلا ومرحبا.
which model of piezo buzzer is that?
What about the dental floss?
Hello.Can you help me?I have some problem.When I write :
tone(peizoPin, 3000)
and push verify button the aplication write to me :
"tone"was not declared in this scope
Can you help me?
how do i use the random function with it? can you give help? :)
Can I use it to stop dog barking? thanks
Is the intro song an actual full length song? If so whats the name? Thanks
The attribution link is at the end of the video. It was a remix of those tracks.
@@programmingelectronics thanks!
how do i add a push button to this to make the tone start and stop when i want?
just did this...super EASY! ...now my dog is pissed at me though haha
i dont have 220 ohm resistor, can i use 560 ohm resistor?
+razell de guzman Give it shot!
Hi, i tried the same code and same pin. But duration does not work. I tried many times with different pins .please help!
Is there any way to make it do sound, instead of a tone? Such as saying the letter A, over and over again?
waht happens if we dont use resistor?
what frequency should i put to make a BUZZ sound?
You need to sweep at a high frequency.
For example: 800-1000Hz @ 120Hz will generate a buzz.
sir i used tone parameter its not working i mean iam not getting delay help me out sir please
"One hert" :D
audio is only in left earphone and my earphones are not broken XD
how to make sound like ambulance siren using tone function
TRY THIS BRO :)
void setup() {
}
void high(){
for(int i=1000;i=1000;i--)
tone(11,i,1000);
delay(10);
}
void loop(){
high();
low();
}
Does it work on nano?
I see no reason why it shouldn't.
Am I the only one that didn't knew that this even existed ?
how can I make notes?
Great question - I look into making a video on that...
what is the dental floss for I'm so confused
It was a lame joke - trying to keep these fun.
why they didn't call it freq ..
int piezoPin = 8;
int del = 1000;
void loop() {
tone(piezoPin, 2500, 200);
delay(del);
del -= 20;
}
...💥💥💥
Man this is just so annoying that the sound of this video is Mino. It really hearts my ears.
mississippi😂
MAKE SOME NOISE, PUT YOUR HANDS UP IN THE AIR!!
I have tinnitus that sounds like an 8800 tone.
That sucks.
2020 its not fantastic :(
My neighbours are breeders. Their children make enough noise 😑
Hello can you give your email?
just did this...super EASY! ...now my dog is pissed at me though haha
