本程序基于51单片机通过前方的红外探头来检测地面的信号,根据道路的要求,当道路为白

色时，红外接收到信号，与地面检测的红外相应端口低电平,当道路为黑色时 ，与地面检测的红外相应端口为高电平,我们就可以根据这和判断条件来进行 道路黑白线的寻找.-This procedure is based on 51 single chip microcomputer through the infrared sensor to detect the ground in front of the signal, according to the requirement of the road, when the road is white
