Name: Voice-activated LED melody light;
Working voltage: 3-5.5V
PCB board: FR-4 A grade glass fiber board
Dimensions: 3CM*2.3CM
Circuit function:
After the kit is successfully produced, 5 LEDs will flash with the rhythm of music or other sounds, and they can be placed near the speaker, allowing the lights to accompany the music to dance!
The voice-activated LED melody light is mainly composed of a power supply circuit, a microphone amplifier circuit, and an LED light-emitting circuit. The power is input by J1, and C1 is filtered for circuit use. MIC1 converts sound signals into electrical signals, which are amplified by C2 coupled to Q1, and the amplified signals are sent to the base of Q2. Q2 drives 5 LEDs to emit light. The louder the sound, the brighter the LED lights.
