Do I need a 1 ch relay module ?

Hello, sorry i wanna ask something, where's the sound?

Hello there, great video! Could I know threshold value of the sensor? What does it mean by 200? It is by value of hertz or decibel? or other? thanks..

Thank you for providing language, not music.

hey, why does the other LED of my KY-038 doesnt turn off like yours?

Thank you! It was really simple and helpful, you really saved my project

have done exactly what you have shown and it simply does not work.

Can you explain it in description because I was doing this project for science expo

Check this tutorial if the sensor is not working: kzbin.info/www/bejne/bX6aiWaKj9R_o68

better

thanks for the upload man, this was awesome!

Can you please make one with a relay module included

Wow! what ideas people have.I am really touched

cảm ơn bạn rất nhiều

Hi, i need help. Why when i run the coding, it appear 'A2' was not declared? I copy exactly like yours. THank you.

أهلاً وسهلاً ومرحباً بك-شكراً لك-يتعذر الاشتراك ولا يوجد جرس-يتعذر التعليق-لا أعلم .

pleas bro tutorial program code

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?

Thanks friend. I was worried why my project it doesn't work but this was helpful.

It does not work😢

I will report you....

it doesn't work because he tells me « ledpin was not declared in this scop »

pleaseeee help me before thursday cause i have to submit it

thanks,but it says that keypad.h is in no file or directory

WHERE IS THE FREAKING CODE IT DOES NOT WORK AT ALL!!!!

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.

Thanks!!!!

helppp mine is not working

Like should the adapter be connected to the laptop or can we take out and it will still work

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.

I liked the video, but i have a doubt can i make the project if the flame sensor has 3 pins instead of 4 pin @krproject8917

my arduino cauught on fire

Cam you tell some more info abt the potentiometer??plsss

hey can you share your insta handle or personnel email ..i need a help regarding my mini project

threshold value is for what

Bro i have one doubt . Could you please givee u r mail id yo discuss it

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

'Serial' was not declared in this scope 'A2' was not declared in this scope ihave this type of error how to solve it

mail id please

Amazing

Thanks Bombay., IT students in the Philippines are always watching Indian Tutorials incomes of IT major subjects.
