智能小车学习第四课:小车黑白循迹

Objection 在本课中我们将带领大家一起学习智能小车黑白循迹,使小车能够沿着白底黑色轨迹运动,就像火车在铁轨上运动一样。我们通过5个黑白红外循迹模块判断小车的位置,避障工作原理:即利用红外线在不同颜色的物体表面具有不同的反射性质的特点,在小车行驶过程中不断地向地面发射红外光,当红外光遇到白色地板时发生漫反射,反射光被装在小车上的接收管接收,此时模块信号指示灯亮起,模块信号输出引脚输出低电平;如果遇到黑线则红外光被吸收,小车上的接收管接收不到红外光,此时模块信号指示灯熄灭,信号输出引脚输出高电平。为了使小车循迹时候能后运动平滑一些,在程序中使用了PID算法来调节小车速度。 Parts and Devices 在本课中需要 用到一下器件 Device Name picture qty Arduino UNO 补部件图片100 x 100 1 Motor with wires 补部件图片100 x 100 4 L298N MOTOR driver module 补部件图片100 X 100 1 Box for 18650 3.7V battery+ DC power connector
