DIY SOUND METER in decibels using KY-038 Sound sensor module, 0.96" OLED Display and arduino nano

code link!
drive.google.c...
if you need to know how i have caliberated it to decibels and decibels to bar graph mail us at [e-mail]

[@putrifzag9770]

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.

[@idmncc]

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?

[@terrykang7737]

please access for the code !

[@armanahmed1794]

Really great work momin Bhai::

[@MOUNTDYNAMICS]

Thank you 😊

[@MiG-25IsGOAT]

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

[@syaduinotech3681]

Thanks.. for sharing.. love to try it

[@MOUNTDYNAMICS]

You’re welcome 😇

[@soriatel]

How to calibrate it?

[@arwenitaofdoom9041]

The code then? how did you calibrate it? mine is stuck at 0 db and i don't know how to fix it

[@lawrencechin2739]

I would like to request your code? Thank you

[@tl6817]

Please grant access to the code. Thanks!

[@razeenrazman6580]

why there is an error compiling for board arduino nano when i tried to compile thd coding ?

[@gorkazamorano8471]

Why is fixed on 40 dB? If there's no noise it should be less dB

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

Why it doesn't go 0dB during silence?

There is no such thing as "0dB", it is 40 on average
