Voice control car movement

Overview

This circuit board is a voice system circuit board. The car can be controlled to move forward, turn, retreat and other operations through the control drive board L9110 or L298N.
Through voice, the IO port of the VC-02 module inputs the corresponding level signal or PWM signal to control the driver board L9110 or L298N, and then controls the car to move forward, turn, retreat and other operations.
The circuit board has three power supply methods: the first is to connect a 3.7V lithium battery through the CN1 interface, this method can lead to 7V voltage through the H4 pin header; the second is to be powered through the TYPE-C interface, this method can be used through the H6 header The pin leads to 5V voltage; the third method is to input 5V voltage through the H6 pin header to power the system board.
The VC-02 module can use the serial port programming method, that is, use the TYPE-C interface to connect to the host computer to complete the programming work. For relevant information about VC-02, please refer to the official website of Anxinke Technology.
