ESP8266Wi-Fi模块在智能小车控制中的应用

为了实现无线模式遥控智能小车,以STC89C52作为主控芯片,搭配ESP8266无线Wi-Fi模块,通过串口使用AT指令向ESP8266模块发送指令,配置相应的地址与端口号,将ESP8266模块设置为TCP服务器的同时开启Wi-Fi,通过手机APP连接上ESP8266模块操控小车。同时还具备PWM调速功能,也可通过重力感应来调节小车的速度值,实现了无线遥控小车姿态的目标。

In order to realize remote control intelligent car by wireless mode,STC89C52 chip is used as the main control CPU,and wireless Wi-Fi module ESP8266 is used in this paper.Send commands to ESP8266 through the serial port AT commands,configure the corresponding address and port number,set ESP8266 as TCP server and enable Wi-Fi at the same time,and connect ESP8266 to control the car through the APP.PWM speed control function and adjusting the speed value of the car through gravity sensor are also equipped.The purpose of wireless remote control car posture has been realized.
