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.
