drive.google.c...
if you need to know how i have caliberated it to decibels and decibels to bar graph mail us at mountdyanmics@gmail.com
Excuse me, i wanna ask how you determine the max & min value? and what's the source formula of calibrated dB in map() function?
thanks.
I have an idea: "Make a door lock that incorporates passcode, fingerprint, and GMS, which you can access on both sides of a door."
Can you do that please?
please access for the code !
Really great work momin Bhai::
Thank you 😊
Hello sir can you please share the code? Or at least tell how to download it or where?? All the users watching this video wants the code. How do we get it? can you please make it public or something? it should be enough for some of us if you told us how to convert analog do dB
Thanks.. for sharing.. love to try it
You’re welcome 😇
How to calibrate it?
The code then? how did you calibrate it? mine is stuck at 0 db and i don't know how to fix it
I would like to request your code? Thank you
Please grant access to the code. Thanks!
why there is an error compiling for board arduino nano when i tried to compile thd coding ?
Can you please change this google drive link to be public? that would make this easier or please grant access from my request. thank you!
yes please
He loves the comment but doesn't answer
Code please ?
Nice video momin all the best
Thanks
Why is fixed on 40 dB? If there's no noise it should be less dB
Hello, please grant me access to this code, I need it for my college projects.
Thanks ❤️
Please send me the code
Hello, please acept me to see the code. It IS so important for a school project
Please grant access
Please grant me access to code.
Can you provide the circuit digram and components used plz
hello, great work by converting voltage to db level can I get the code please, I'm a student and I need this please
con you give me access please?
Thank you making the video. Half bread board, KY038, arduino nano and OLED display plus your code (which program language is your code . I am trying to build decibel meter to warn the roommate is too loud. Maybe add light bar or a flashing red light when it reach number. Do you think this project will work? Can I please have access to the code? Thank you
Hell sir, can i get access to the drive in description
Thanks
Hey please grant the access I need urgently
Can you please grant access of the code?
helo can you share the code
Crazy !
Please grant the access to the drive link
Could you give me access to the code please?
Amazing work! I was wondering if you could grant access to the code.
Thanks in advance!
It's in the description!
Hi
Please grant access to code. Thanks
Code please!??
can someone provide the codes here? thanks.
plz code
sir, please grant access
excuse me, grant me access to the code
Why it doesn't go 0dB during silence?
There is no such thing as "0dB", it is 40 on average
