這是之前課程設(shè)計(jì)做的遙控小車，簡單的控制電機(jī)轉(zhuǎn)速使小車前進(jìn)和后退，左轉(zhuǎn)右轉(zhuǎn)也是參考了網(wǎng)上別人的，有需要的可以看看，哪里有不足也請(qǐng)指出

ATMEGA168單片機(jī)+L298仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）

單片機(jī)源碼：

int Foreward_key=2;//正轉(zhuǎn)按鈕
int Reverse_key=3;//反轉(zhuǎn)按鈕
int Stop_key=4;//停止按鈕
int Trunleft_key=0;//左轉(zhuǎn)按鈕
int Trunright_key=1;//右轉(zhuǎn)按鈕
int Foreward_led=5;//正轉(zhuǎn)指示燈
int Reverse_led=6;//反轉(zhuǎn)指示燈
int Stop_led=7;//停止指示燈
int pinI1=8;//定義電機(jī)1正轉(zhuǎn)接口
int pinI2=9;//定義電機(jī)1反轉(zhuǎn)接口
int pinI3=13;//定義電機(jī)2正轉(zhuǎn)接口
int pinI4=12;//定義電機(jī)2反轉(zhuǎn)接口
int speedpin=14;//定義EA(PWM調(diào)速)接口
int speedpin1=14;//定義EB(PWM調(diào)速)接口
