Circuit function:
The red terminal of the Bluetooth module is 5V power supply, the white terminal is for 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 follow the rhythm of the sound (the speed of the sound flashes and moves. After the welding is successful, you can feel the beautiful 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 indicator circuit. The power supply uses 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 pushes the LED to emit light , The louder the sound, the higher the brightness of the LED, the faster the water flow.

Notice:
All parts need to be installed by yourself. The outer cover is transparent if the paper is torn off. The whole set of bluetooth speaker kit is equipped with uSB power cord. The bluetooth circuit boards are all welded. You only need to connect the wire and assemble the sound control board. The power supply can be powered by a mobile phone charger or a computer 5V. The sound quality is better when using a current of 2A. .
