ESP8266制作远程遥控车_esp8266 遥控车代码

材料：

ESP8266 12F一块（10元出头）

L298N电机驱动模块一块（10元左右）

12V电源（15左右）

杜邦线若根

小车底盘+电机+螺丝+轮子（网上套件也就20多块钱）

接线：

8266的VIN针脚用杜邦线接L298N的5v孔

8266的G针脚用杜邦线接L298N的GND孔

8266的D0,D1,D2,D4针脚分别接到L298N的IN1,IN2,IN3,IN4针脚

左边两个电机分别接到OUT1，2口

右边两个电机分别接到OUT3，4口

不会接的有详细教程，下面放链接

把代码复制到arduino，需要的库自己下载，很基础的东西，我就不说了，不会的网上搜一下

这里强调一下就是代码上传的时候，工具里的flash size后面不能选择no SPIFFS，一定要注意，很多人就是因为没有注意这个地方，导致每次断电重启后，都需要重新配网，设备无法记住WIFI的账号密码！
