Circuit function:

*The red terminal of the BT module is the 5V power supply, the white terminal is the direct connection channel of the speaker, the red wire is the positive pole +, and the black wire is the negative pole -. As music or other sounds sound, the LED lights will move with the rhythm of the sound (the speed of the sound and the volume of the sound). After the welding is successful, you can feel the beautiful melodic combination of sound and sound.

*Circuit principle: Voice-controlled LED melody. The light circuit consists of a power supply circuit, a microphone amplification circuit and an LED lighting indication circuit. The power supply uses two batteries, and the MIC converts the sound signal into an audio signal. The electrical signal is amplified by coupling Q1 and C2, and the amplified signal is sent to U1, which drives the LED to emit light. The stronger the sound, the brighter the sound, and the speed of the LED and water speeds up.

Notice:

*All parts must be installed by yourself. The fetal tissue is transparent after being torn off. The entire BT speaker kit is equipped with a USB power cord, and the BT circuit board has been welded. You only need to connect the wires and assemble the sound control board to use it. The power supply can be used to power a mobile phone charger or a 5V computer. The 2A current power supply provides better sound quality.
