The louder the sound, the more the LEDs are lit from bottom to top. As the sound fluctuates, the LEDs will jump with the music, especially when playing DJs.

The use of a separate comparator circuit is slightly more complicated, but the structure and principle are easier to understand.

With anti-reverse protection diode, it can effectively prevent the polarity of the power supply from being reversed, which will make the circuit burn out, which is more suitable for DIY.

 

 

About signal input: The board has its own microphone. It does not need to connect the audio signal. It can sense the external sound source to control the flashing of the LED lamp bead. The disadvantage is that the sensitivity is not as good as the line input, and it is easy to be affected by other external sounds.

If line input is required, this step is about the audio signal (such as the earphone hole of the mobile phone or computer, it can not be connected to the output of the amplifier or the speaker), the microphone can be removed, and the signal is directly introduced from the microphone. If the light is fully illuminated, Then adjust the potentiometer (reverse clock reduction) recommended this connection.
