Thanks friend. I was worried why my project it doesn't work but this was helpful.
It's working good for me! Thanks for the tutorial.
For some people in comment section who did not get output -
1. Capital 'S' in Serial.begin(9600) should be used
2. Newly bought sound sensor should be adjusted to normalcy
- by screwing the potentiometer in anti clockwise (Analog output pin nearer to you) direction for "20 turns" or so
Brother even I also did it in same way but the LED is on through out all time it doesn't react to sound can plz explain?
Thanks Bombay., IT students in the Philippines are always watching Indian Tutorials incomes of IT major
subjects.
Thank you! It was really simple and helpful, you really saved my project
What if you power your arduino uno with an external battery. Would you still need to connect the plus power pin of the sound sensor to the 5V input of the arduino uno? Or would you have to connect it to another input?
Can it be programmed to detect certain sound signal patterns that work as an encrypted "message", which then can be translated into a code that unlocks the encryption, and activate a certain command?
*The device would detect any sound, but woun't initiate that specific command until it has received the proper sound signal.
Is there a way to use the sound output via a mini stereo cord from say a phone or computer jack and read it instead of reading it in open air via the microphone module?
From same code can we add to switch relay to turn on light or other devices? Do you have any video of such?
This is amazing!! It worked perfectly for me!!
How does it plz explain, my LED always on it doesn't react to sound though any idea, if you have did it?
Thanks mate, very clear and useful 👍
It would be nice if you could show also the Serial Monitor
All the best
thanks! also,why did you use "serial begin9600"? i think its wasn't necessary for this project, but correct me if im wrong
thanks for the upload man, this was awesome!
Like should the adapter be connected to the laptop or can we take out and it will still work
Hey, I have one question.. I have another component connected to the Arduino, so the 5V place is already taken. How to connect the Sound Sensor + then?
If wonder if this would work as an early-alarm? If you were to somehow glue this behind a lock, or a window?
Is there a way to make it detect ONLY high (or only low) pitched sounds? That would be amazing for a security system...
2 question,..1st question - what do i put in threshold to enable the LED when i say "hi" ?...2nd question - what application did you use in your computer ?,thx.
Still i am not getting how can connect the digital output pin of the sound sensor with the analog pin of the arduino.
Can sound be recorded and sent across the house to receivers and sensor's? Once you pass them?
How to connect two sound sensors at a time and read them simultaneously?
do you can do it with 3 pin's of the sound detector
How can i use this sound sensor for more applications with different power consumption?
It doesn't make any sanse you connect D0 on the sensor to analog input on arduino. When you check readings from D0 (sensor) with command Serial.println (soundsens); it will show you readings like 1023 (and no chance will you change with trying to adjust the potenciometer). BUT if you connect the wire to A0 (instead of D0) on the sensor you will get accurate readings. THEN you can spin the potenciometer and try to put it to 150-160 while watching its read on Serial monitor. Then when you clap your hands the readings will go above 200 and the LED will shine.
You can do it however you want. There are no restrictions in programming and electronics.
It didnt work i got the program perfect yet still whenever i apply power the led turns on. Explain if you can thanks sir.
@@krproject8917 what he is saying is right. Digital output from sensor means high or low. There is no in between values . You have to use Analog output of the sensor
@@micahproulx1989 use Analog output of the sensor
@@toddmoore112 I tried that, whenever i apply power it just turns on. Thanks, Micah.
thank you so much my friend
Can we use PIC18F4520 microcontroller instead of Arduino Uno..??
it was really helpful, and thank you for the code explanation
Its coming error in else line that is in the end
:exit status
Expected unqualified id before 'else'
When you copy his code don't forget to change the A# pin to which ever number you plugged in your cable to. A very pivotal part that was missing.
Thanks bro
Can I use gy max4466 for this project?
Hello, may I ask how to let my Arduino connect with Bluetooth and resonate sound?
nice tutorial.
mmm i have a trouble. in your tutorial, you find high/low sensor. if high then led on. can i get a frequency this sensor?
Michael Indra Pramana you can print the sound sens value and see if it gives u the data.
Serial.println(soundsens);
No bullshit, no ambiguity, and you spoke English because the title is also in english. 1100/10
whys my led doesnt light . all are the same with the video? thanks for the help
man, thank you very much after seeing your video I was able to find the error in my project and now I was able to execute everything in compliance, thank you again and continue making videos like this, a hug for you from Belém-Pará-Brazil.
Happy to help.
Hello!! Which microphone/sound sensor did you have specifically used??
Actually I have to detect whether sound exceeds a threshold value or not....
Thanks in advance!!!
can this be done with servos? If so, how can i do this?
How many can set led for mega?
Can do separately?
Thanks for the video. My led is always on. I tried both AO and DO from sound sensor and connected to A2. Also tried adjusting the potentiometer.
Same problem
Hey, idk if you still need this, but try adjusting ur threshold in the int's at the top. Everyone has a different value, but for me it was 1015. you will have to play around with it a bit, but i hope this helps.
@@tameemullas5868
Can I use same sound sensor with raspberry pi 3b+?
Hi, i need help. Why when i run the coding, it appear 'A2' was not declared? I copy exactly like yours. THank you.
Great ,it's working properly
Cam you tell some more info abt the potentiometer??plsss
How can I use this in a system that deters barking dogs? I currently have a system I wired together that runs high pitch piezo tweeter speakers on a remote but that doesn't work when I'm not home to activate it. The over the counter bark deterrents are useless. I need it to stay on for 30 seconds when it detects noise but no shut off when it detects the second bark. Any ideas?
U get it ?
Thank you so much , it's really work ❤️💪🇩🇿
Please explain the mi how to do this please send the coding
Bro..., in need aurdino program code for my project work.... If possible can you provide it
where we use this type of projects???
I tried for about an hour adjusting the potentiometer but the light that is only supposed to go off from sound is unable to to turn off. Could something be faulty with my sound sensor? It looks like the exact same one from the tutorial. Since this is the case, the LED on the UNO is constantly turned on as well as the 2 LEDs on the sound sensor. Any advice is appreciated. I've watched the tutorial 3 times now.
Use the analogue pin of the sound sensor...not digital
@@zannelleooko1745 Thank you!
Had the same problem!
Can we record sound using this sensor?
This video is very usefull for me.Thank You
cảm ơn bạn rất nhiều
Does it recognize voice command?
What should I do if I have ESP32 instead of Arduino?
'Serial' was not declared in this scope 'A2' was not declared in this scope
ihave this type of error how to solve it
why is led always on on my project what is the problem of this? even without sound the led is always on
Brother I did it in the same way as you but its not working, I copied the program and pasted it, but the LED is on it doesn't react to sound , connections are also made properly, can you give any idea for it?
Plz reply me brother
board at com5 is not avilable error is coming. can u pls help
Can we connect motor instead of light
Hi guys, how do you make a guitar sound catcher?
is there a way where the led would turn on at a certain decible?
so like:
if (decible = >60)
{
digitalWrite(LED, HIGH);
}
else
{
digitalWrite(LED, LOW);
}
}
can I see the full code?
My sound sensor circuit isn't working, the LED lights up and stays on. It doesn't light up or turn off when it is suppose to. There is no error in the code, as the Arduino IDE says there is no error. The connections appear to be good as well since I double checked. The only difference is that I am using NANO to save space time and money.
Hey, idk if you still need this, but try adjusting ur threshold in the int's at the top. Everyone has a different value, but for me it was 1015. you will have to play around with it a bit, but i hope this helps.
Who to adjust potentiometer
Can we use nano aurdino?
I have a similar sound sensor that is red. However I am having trouble with it it only turns on the LED when it is directly facing it and close, and also it reacts much better to claps. I am trying to make it turn on the LED to the basic sound of the buzzer, so like a pin that goes on and off. I would like it to be able to react to the sensor when it is relatively far away, at least 1 ft for this stage but ultimately i would like it to detect the sound at least 20 ft away while both are underwater. Do you think that the sensor was not working because the sensor had a fault? or is it just that theses are not that sensitive to begin with? Thank you!
Yes, these are not very sensitive. But, you can still try adjusting your potentiometer.
Best of luck.
You helped me so much
Creative video, thanks for sharing :)
My sound sensor heated what does it mean?
Can you please give us the circuit in proteus !!?
well done bro ,thx
Can we calculate the decibel
Nice bro more learn about this kee it up
I can't adjust the potentiometer there. The led light besides it does not turn off. Any help?
i have the same problem :(
hey, why does the other LED of my KY-038 doesnt turn off like yours?
ive been twisting the potentiometer for a long time now
thank you brother
you are a best
Hi I’ve done exactly what you instructed but the LED is constantly on. I’ve tried adjusting the sound sensor but does not help.
You must adjust your potentiometer. First, turn it clockwise and try. If it doesn’t work, turn it anti clockwise and try.
K&R project Thank you. I figured it out. I did not realize you had to turn it a certain direction to adjust , I also had to turn it SEVERAL times for it to work. I appreciate your response.
My LED is on but no clap...Whats the problem?
Need help. I've done everything as you said, i've copied the code and connected all, same as you, But the led is everytime on, i cant find the way to make it turn off and then react to a song or sounds. What could be the problem ?
Pls send me the code. engrdapo@gmail.com
Please try adjusting the Potentiometer. Also, check if you've delayed the program elsewhere using the "Delay" function.
i have same trouble you can resolve??? how plzz
same problem with me
hi how are you sorry for disturbing i copy and past the cod every thing is ok but the led is on all ways can you help me plz
Check the small LED on the sensor. If it is turned on with giving any sound input, your potentiometer is not adjusted properly and the condition of the code is always satisfied. Adjust it such that the Sensor's led turns on only when you give some input. This will solve the problem. Sound sensor becomes problematic when the potentiometer is not adjusted properly.
K&R project hi I adjusted and the led sound sensor is on
The led sound sensor is on and the led output is also on also if there is sound or no sound the output led is always on
Hello the output led is always on if (their is sound or not )
Kalau pake arduino nano bisa ya ?
threshold value is for what
Pls do for RGB strip (adressable)
Can we make a sound sensor work on a specific soundn
adjust the sensitivity by screwing the blue thing
Thanks man... saved my ass...
Hi. Could anybody please post a build of Arduino decibel meter for an Airgun with shown Max last reading. Small size would be preferable, possibly Arduino Nano and Oled screen. Most Android Phone Apps don't work correctly as the phone kills the Microphone sensitivity automatically and sampling isn't fast enough. Thanks in advance. Good Video BTW.
thank u bro
I am 12 years old, I am very interested in Arduino. I was succeeded in this. Thank you a lot.
It is a very clever component
do we really need to put the led on the board?
what it is for?
hello .. my led is on and i've tried to adjust the poteniameter but it doesnt work !! PLEASE HELP
First, turn it clockwise and try. If it doesn’t work, turn it anti clockwise and try.
can you set the sound sensor to pick up a specific sound?
yeah specific range
Range in which unit
Tinkercard mein sound sensor available nahi hai kaise kare
How to put a buzzer instead of led
Whear is delay program
Hello,Your explanation is really great and it is upto the point ..I have a doubt,hope u will clear it
I want to set a threshold value and based on that, if the sound exceeds the threshold (then the Arduino needs to command GSM to make alert call). Is detecting higher range sounds be done by modifying your circuit and code a bit???
For this, can you tell me what are all the requirements I need to have?
Thanks in advance!!
Yup. You can change the threshold value for different ranges. Just remember that this sound sensor cannot detect wide variety of input as it is just a small sensor for small projects.
Sound sensor with sargo 180° Pogroms..... Plz send me..
Cool dude
hi can you write code here?
The code is complet?
amazing thanks
You have a new sub.. Good explanation. Keep up the good work.
how did you get paid to write this. This guy is totally incomprehensible
loved the video bro! keep making more! Its amazing the things God created
How can i detect a particular frequency using this sensor
yeah thats my question too did you figure it out?
please give a code link
Hello Man nice job
Could you show how to do it with a 5050 LED strip?
Do you mean use 5050 led strip instead of a led?
K&R project yes a RGB strip , no RGB LED , I ve tried with npn transistor but I cant light Up the 3 colors 🤔
It maybe because the arduino’s power supply is not enough. Try by using two or more transistors.
With a transistor per color is ok
Thanks
