10-segment crystal column spectrum light through microphone induction LED light fluctuates with the volume of music especially at night full of dynamic feeling. Long-term animation multiple audio effects high sensitivity. In the circuit the adjustable resistor RP1 is used to adjust the amplification of U1A that is to adjust the sensitivity of the volume column. The capacitor C2 and R3 form a delay circuit which can form a slow descent pattern on the volume column making the volume column look more intuitive.
