Circuit function:

The red terminal of the Bluetooth module is powered by a 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, LED lights follow the rhythm of the sound (the speed of the sound shines and moves. After successful welding, you can feel the beautiful melodic combination of sound and light. Circuit principle: voice-controlled LED melody light circuit consists of power supply circuit, microphone amplifier circuit, LED light-emitting indicator circuit, the power supply uses two batteries. MIC converts the sound signal into an electrical signal, which is coupled to Q1 by C2 for amplification. The amplified signal is sent to U1 and U1 drives the LED to emit light. The louder the sound is, the higher the brightness of the LED, the faster the flowing speed is.

Note:

Parts are all need to be installed by themselves. The shell paper is transparent when torn off. The whole set of Bluetooth speaker kit is equipped with uSB power cord. The Bluetooth circuit board is welded and can be used only by connecting the cord and assembling the Sound Control Board. The power supply can be supplied by mobile phone charger or computer 5V, and the sound quality of the power supply using current 2A is better.

Reminder: Please strictly follow the product instructions. Incorrect use and wiring will cause the power amplifier to fail to operate normally or damage the power amplifier.
