LED audio level indicator / volume meter - blue

This module is used for dynamic display of the music spectrum. The louder the sound, the more the LEDs light up from bottom to top, creating a cool glowing effect. 

Completely soldered, this is not a soldering exercise.

The circuit board is equipped with a microphone, so no direct audio connection is required. Switch on the module and it lights up immediately when a sound is heard. 
The sensitivity of the audio input can be adjusted using the potentiometer.

Equipped with a reverse polarity protection diode, it effectively prevents the circuit from burning out due to the reverse polarity of the power supply.
