Function description and design principle:
This system uses STM32f103 single-chip microcomputer to control the four-way steering gear through PWM, and communicates with the ld3320 voice recognition module through the serial port. The voice recognition module uses preset voice entries, including garbage names, and wake-up instructions. The single-chip microcomputer classifies the preset garbage names and controls the steering gear to rotate to achieve the purpose of simulating opening the garbage can. At the same time, it can drive the voice broadcast module to play corresponding voice prompts.
System composition = STM32F103C8T6 + LD3320 voice recognition module + JQ8900 voice broadcast module + four-way SG90 steering gear.
Information description:
