智能小車各獨(dú)立模塊 紅外遙控 電機(jī)驅(qū)動 超聲波 紅外尋跡

1、相信進(jìn)來的都是想學(xué)習(xí)和制作智能小車的，最近也在學(xué)習(xí)智能小車，我們的小車功能時紅外遙控小車，小車避障，小車尋跡?，F(xiàn)在將學(xué)習(xí)過程中所發(fā)現(xiàn)的一些比較好的代碼與大家分享，希望能對大家有所幫助。紅外遙控#include <stc15.h>#include <gpio.h>#include <intrins.h>#define uchar unsigned char#define uint unsigned intsbit IRIN = P32; /紅外線一體化接收頭接收端sbit out1=P21;sbit out2=P22;sbit out3=P23;sbit ou
