DIY Sound Control LED Music Spectrum Electronic Kit Crystal Column Audio Display PCB Soldering Practice Kit LM339 LM358 DC5-12V

Description:1. 10-segment crystal column spectrum light. Microphone-sensing LEDs pulse and fade in rhythm with music volume.2. Dynamic nighttime use. Features extended animations, diverse audio effects, and high sensitivity.3. In the circuit, adjustable resistor RP1 modulates U1A's amplification gain—adjusting the volume bar's sensitivity.4. Capacitor C2 and resistor R3 form a delay circuit, creating a slow-falling pattern on the volume column for enhanced visual clarity.5. Easy assembly: Includes detailed instructions for DIY enthusiasts, requiring no advanced electronics knowledge.Product Specifications:Supply Voltage: DC 5~12VLED Quantity: 10 multicolor LEDsProduct Dimensions: 1465533mmPCB Dimensions: 14628mmNote: Shipped as loose components requiring self-assembly.Package Contents:DIY Kit1Includes:Surface-mount diode 1N4481SMD Resistor 4.7K11SMD Resistor 33K2SMD Resistor 36010SMD Resistor 100K1SMD Capacitor 1052Microphone13296 Positioner1LED 5mm10SMD Integrated Circuit LM3581SMD Integrated Circuit LM3392Power Connector1
