Product Overview: The LED flower section uses a STC15F2K60S2 microcontroller with push-pull output to control the on/off state of each LED, creating a running light effect. The chassis includes a Bluetooth module powered by an ASM1117-3.3V voltage regulator to ensure stable operation and prevent interference from the running lights. The Bluetooth module receives audio signals, which are amplified by an HT6872 audio amplifier IC for speaker output. Three microcontroller IO ports interface with the Bluetooth module’s control buttons, enabling functions such as play/pause and volume control via logic-level timing. One additional IO port connects to the Bluetooth audio output for analog-to-digital conversion (ADC), enabling sound-reactive lighting effects.
