Sound-Controlled LED Melody Light DIY Kit with battery pack

Sound-Controlled LED Melody Light DIY Kit with battery pack

€1,90

Discover the fun of electronics with this engaging DIY electronic kit! This sound-controlled LED melody light is perfect for beginners and enthusiasts alike, offering hands-on experience in building a creative light project. The kit includes all the essential components to assemble a fascinating LED display that reacts to sound and music, creating beautiful patterns in sync with the melody.

  

Parameters

Model: SKD5

Operating Voltage: 3–4.5V

PCB Material: FR-4 Fiberglass Board

Dimensions: 34 x 34 mm

  

Circuit Function

Once successfully assembled, the five LEDs in this kit will flash in sync with the rhythm of music or other sounds. Place it near a speaker, and watch the lights dance to the music!

  

Circuit Principle

The SKD5 sound-controlled LED melody light consists of three main parts: the power circuit, microphone amplification circuit and LED light-emitting circuit. Power is supplied via J1, with C1 filtering for circuit stability. MK1 converts sound signals into electrical signals, which are coupled through C2 and amplified by Q2. The amplified signal is sent to the base of Q1, driving the five LEDs to emit light. The louder the sound, the brighter the LEDs glow.

 

Kit Components

  • PCB board with all necessary components
  • One instruction manual
  • Bonus: 2-pin power cable
  • Battery holder included
