2. Power supply 5V (USB interface power supply)

3. High brightness: all use authentic huge high-brightness LEDs

4. Driven by a comparator circuit, the spectrum effect is better, and the brightness is not false and clear.

5. Sensitivity to sound, adjustable with potentiometer

The louder the sound, the more the LED lights up from bottom to top. As the sound fluctuates, the LED will jump with the music, especially when playing a DJ.

Using an independent comparator circuit is slightly more complicated, but it can be displayed accurately. With an anti-reverse protection diode, it can effectively prevent the circuit from being burned due to the reverse polarity of the power supply, which is more suitable for DIY.

It can be placed beside the computer, beside the TV, beside the home stereo, inside the portable Bluetooth speaker of the power amplifier, beside the car screen, the notes that beat with the sound.
