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.
Features:
- Size: length 16cm * width 1.6cm;
- Lamp beads: 5mm round head fog LED, the light is even and not glare (6 from the bottom to the top, 6 in blue, 4 in yellow, 4 in red);
- Power supply: DC 5V~12V, the board has a microUSB socket, you can plug in the power supply with the corresponding mobile phone charging cable, and also reserve 2 pad ports;
About signal input: The board has its own microphone, which 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 easily affected by other external sounds.
If you need line input, this step is about the audio signal (such as the phone or computer's headphone jack is, can not be connected to the output of the amplifier or the speaker, the signal is too strong, if it is really connected, you need to attenuate the signal), you can Remove the microphone and the signal is directly introduced from the microphone. If the light is fully illuminated, adjust the potentiometer (reverse clock reduction).
