Chassis Blue-tooth part of the use of voltage regulator chip ASM1117-3.3V for the Blue-tooth module to provide a stable voltage, to avoid the operation of running lights affect the Blue-tooth module work. Blue-tooth module receives Blue-tooth audio signals, HT6872 chip constitutes the amplifier circuit Blue-tooth received audio signals for amplification output. The flower part uses STC15F2K60S2 push-pull output to control the light and dark state of each LED to achieve the effect of running lights. Product Overview: Three IO ports of the microcontroller are connected to the Blue-tooth key part, manipulating the high and low levels of the microcontroller IO ports as well as the level duration, so that the microcontroller can also control the audio, and one IO port is connected to the Blue-tooth output part for ADC acquisition, which is used to realise the rhythmic effect of the running lights.
