1. Design the circuit: Connect the Bluetooth module to the amplifier and speaker. Integrate the microcontroller to receive audio data or signal for LED control.
2. Set up the microcontroller: Program the microcontroller to read audio input or Bluetooth signals and control the LED strip accordingly, creating visual effects that sync with the music.
3. Assemble the power system: Connect the lithium-ion battery to the charging module and boost converter to ensure stable voltage for the speaker and LEDs.
4. Wire all components: Carefully solder and connect the Bluetooth module, amplifier, speaker, LEDs, microcontroller, buttons, and power system according to your circuit design.
5. Test the electronics: Power on the system, pair with a Bluetooth device, play music, and observe the LED visualizer response. Debug and adjust code or wiring as needed.
6. Create and prepare the enclosure: Design or modify a box to house all components securely, allowing openings for speaker sound, charging port, buttons, and LEDs.
7. Mount components inside the enclosure: Secure all parts inside the box, ensuring good cable management and accessibility.
8. Final testing: Verify Bluetooth connectivity, sound quality, LED responsiveness, and battery charging functionality.
9. Optional enhancements: Add features like volume control buttons, battery level indicators, or customizable LED patterns through additional programming.
