Circuit function:
The red terminal of the bluetooth module is 5V power supply, the white terminal is the left and right channels of the speaker, the red wire is positive +, and the black is negative -. With the sound of music or other sounds, the LED lights will move with the rhythm of the sound (the speed of the sound and the size of the sound. After the welding is successful, you can feel the wonderful melody combination of sound and light. Circuit principle: voice-activated LED melody The lamp circuit is composed of a power supply circuit, a microphone amplifier circuit, and an LED light-emitting indicator circuit. The power supply adopts two batteries. The MIC converts the sound signal into an electrical signal, which is coupled to Q1 through C2 for amplification, and the amplified signal is sent to U1, and U1 drives the LED to emit light. , the louder the sound, the higher the LED brightness, the faster the water flow.
