Product Overview: The LED flower section uses a microcontroller with push-pull output to control the on/off state of each LED, creating a running light effect. The chassis incorporates a 3.3V voltage regulator (ASM1117) to supply stable power to the Bluetooth module, preventing interference from the running lights. The Bluetooth module receives audio signals, which are amplified by an HT6872 audio amplifier circuit for speaker output. Three microcontroller I/O ports interface with the Bluetooth module’s control buttons, enabling audio playback control via logic-level signals and timing. One additional I/O port connects to the Bluetooth audio output for ADC sampling, enabling sound-reactive lighting effects.
