Description:
The louder the sound, the more the LED lights up from bottom to top. As the
sound rises and falls, the LED will also jump with the music, especially when
playing DJ. It is more interesting.
The use of an independent comparator circuit is slightly more complicated, but
its structure and principle are easier to understand.
Equipped with anti-reverse protection diode, which can effectively prevent the
circuit from being burned out due to reverse polarity of the power supply, which
is more suitable for DIY.
The red and black wires on the board must be connected to a power supply between
5V and 12V low-voltage DC, and must not be connected to the output of the
amplifier or the speaker wire.
Regarding signal input: The board has a built-in microphone that can inductively
receive external sound sources to control the blinking of the LED lamp beads.
The disadvantage is that the sensitivity is not as good as the line input, and
it is easily affected by other external sounds.
If line input is needed, this step is about audio signals (such as the headphone
jack of a mobile phone or a computer, which cannot be connected to the output of
an amplifier). You can remove the microphone and direct the signal from the
microphone. If the light is on, adjust the potentiometer. (Reverse clock
reduction) This connection is recommended.
LED color: red / blue / green 3 colors mixed light
Voltage: DC 5V-12V (voltage cannot exceed 12v)
