arduino 智能小车(蔽障、蜂鸣提醒、警示led灯，带串口输出)

#define Buzzer 2#define InfraredSensorPin  4#define LedDisp  13void setup(){  pinMode(Buzzer,OUTPUT);//设置输出引脚  Serial.begin(9600);  Serial.println("Start!");    pinMode(InfraredSensorPin,INPUT);  pinMode(LedDisp,OUTPUT);  digitalWrite(LedDisp,LOW);}void loop(){ if(digitalRead(InfraredSensorPin) == LOW)   {digitalWrite(LedDisp,HIGH);  Buzzer_Di(); }  else  digitalWrite(LedDisp,LOW);  Serial.print("Infrared Switch Status:");  Serial.println(digitalRead(InfraredSensorPin),BIN);  delay(1000); }void Buzzer_Di(){digitalWrite(Buzzer,HIGH);//蜂鸣器响delay(200);digitalWrite(Buzzer,LOW);//蜂鸣器关闭delay(200);}

如果没有障碍就不会亮灯和蜂鸣,串口输出就变成1

终于完成了。
