Circuit Principle

Sound-activated LED circuit consists of a power supply circuit,a microphone amplifier circuit, and a light-emitting LED indicator circuit

MIC converts the sound signal into an electrical signal,which is coupled to Q1 via C2 for amplification

The amplified model is sent to U1 by U1 to promote the LED light,the louder the sound,the higher the brightness of the LED the faster the speed of water flow
