wiring description:

White terminal connected to the horn and red terminal connected to the power supply

Bluetooth operation:

turn on the Bluetooth of the mobile phone, and directly scan the equipment, and find "XC

046 click Connect". When Bluetooth is disconnected, it will automatically switch to the USB

flash drive.

Circuit function:

The red terminal of Bluetooth module is powered by 5V power supply, and the white

terminal is the speaker. The red line is positive+and the black is negative-. With the

sound of music or other sounds, the LED lights will follow the rhythm of the sound. After

successful welding, you can feel the wonderful melody combination of sound and light.

Circuit principle:

The circuit of voice-activated LED melody lamp consists of power supply circuit,

microphone amplification circuit and LED luminous indication circuit. The power supply uses

two batteries. MIC converts sound signals into electrical signals, which are coupled to Q1

for amplification through C2, and the amplified signals are sent to U1, which drives the

LED to emit light. The louder the sound, the higher the brightness of the LED, and the

faster the water flow.

Note:

All parts need to be installed by themselves. The shell paper is transparent when it is

torn off. The whole set of Bluetooth speaker kit has been equipped with uSB power cord, and

the Bluetooth circuit boards are all welded, so it can be used only by connecting wires and

assembling sound control boards. The power supply can be powered by a mobile phone charger

or a computer with 5V, and the sound quality of the power supply with current 2A is better.

Tips: Please strictly follow the product instructions. Incorrect use and wiring will cause

the power amplifier to fail to work normally or damage it.
