This module is used to dynamically display 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.
