Details:
  • With the sound of music or other sounds, LED lights follow
    the rhythm of the sound (the speed of the sound) and flicker. After
    successful welding, you can feel the wonderful combination of sound and
    light.
  • Working voltage: 3-5.5V ( if you need a higher working voltage, please add a current limiting resistor on LED)
  • Circuit
    principle: Sound-controlled LED melody lamp circuit consists of power
    supply circuit, microphone amplification circuit, LED luminous indicator
    circuit, power supply by JP input, C1 filter power supply circuit. MIC
    converts sound signals into electrical signals, which are coupled by C2
    to Q2 amplification. The amplified signals are sent to Q1 base. Q1
    drives LED to emit light. The louder the sound, the brighter the LED.
