How to measure decibel levels on the mics


I want to create a very simple application that depending on the decibeles level of the mics, indicate the level using the leds.

Above 40db, blue, above 60 red, for example,

Any ideas how can I do that ? I’ve seen the mic energy

Hi @neoecos,

Interesting application! I guess you should check out main concepts around this, dB, dBA , and the mics datasheet.

Let us know your progress. Would be glad to help. This would be a nice example to add our code.
