Description
The Voice-Controlled LED Melody Light Kit is a fun and educational DIY soldering project that combines sound and light. It consists of a power supply circuit, a microphone amplification circuit, and an LED indicator circuit. Once assembled, the five LEDs flash and dance in rhythm with music or other sounds—the louder the sound, the brighter the LEDs. Place it near a speaker and watch the lights move to the beat, creating a wonderful melody of sound and light.
