1.先把IRremote函式庫(kù)資料夾放進(jìn)Arduinolibraries目錄底下

2.啟動(dòng)IrReceive.pde測(cè)得自己旳紅外線遙控旳碼（在SerialMonitor可顯示IRcode），再將IRcode記錄下來(lái)，然后到程式里面修改成自己旳紅外線碼即可。3.6.2實(shí)物圖四、模塊軟件設(shè)計(jì)4.1循跡模塊程序intMotorRight1=8;//IN1intMotorRight2=9;//IN2intMotorLeft1=7;//IN4intMotorLeft2=6;//IN3intspeedpin=11;//定義EA(PWM調(diào)速)intspeedpin1=10;//定義EB(PWM調(diào)速)接口constintSensorLeft=5;//左感測(cè)器輸入腳constintSensorMiddle=4;//中感測(cè)器輸入腳constintSensorRight=3;//右感測(cè)器輸入腳intSL;//左感測(cè)器狀態(tài)intSM;//中感測(cè)器狀態(tài)intSR;//右感測(cè)器狀態(tài)voidadvance(inta)//邁進(jìn){digitalWrite(MotorRight1,LOW);digitalWrite(MotorRight2,HIGH);digitalWrite(MotorLeft1,LOW);digitalWrite(MotorLeft2,HIGH);delay(a*50);}voidleft(inti)//左轉(zhuǎn){digitalWrite(MotorRight1,LOW);digitalWrite(MotorRight2,HIGH);digitalWrite(MotorLeft1,LOW);digitalWrite(MotorLeft2,LOW);delay(i*30);}voidright(intc)//右轉(zhuǎn){digitalWrite(MotorRight1,LOW);digitalWrite(MotorRight2,LOW);digitalWrite(MotorLeft1,LOW);digitalWrite(MotorLeft2,HIGH);delay(c*30);}voidstopp(intd)//停止{digitalWrite(MotorRight1,LOW);digitalWrite(MotorRight2,LOW);digitalWrite(MotorLeft1,LOW);digitalWrite(MotorLeft2,LOW);delay(d*10);}voidback(intg)//后退{(lán)digitalWrite(MotorRight1,HIGH);digitalWrite(MotorRight2,LOW);digitalWrite(MotorLeft1,HIGH);digitalWrite(MotorLeft2,LOW);delay(g*100);}voidre(intx)//右大轉(zhuǎn){digitalWrite(MotorRight1,LOW);digitalWrite(MotorRight2,HIGH);digitalWrite(MotorLeft1,HIGH);digitalWrite(MotorLeft2,LOW);delay(x*25);}voidle(inth)//左打轉(zhuǎn){digitalWrite(MotorRight1,HIGH);digitalWrite(MotorRight2,LOW);digitalWrite(MotorLeft1,LOW);digitalWrite(MotorLeft2,HIGH);delay(h*25);}voidsetup(){Serial.begin(9600);pinMode(MotorRight1,OUTPUT);//腳位8(PWM)pinMode(MotorRight2,OUTPUT);//腳位9(PWM)pinMode(MotorLeft1,OUTPUT);//腳位7(PWM)pinMode(MotorLeft2,OUTPUT);//腳位6(PWM)pinMode(speedpin,OUTPUT);pinMode(speedpin1,OUTPUT);pinMode(SensorLeft,INPUT);//左感測(cè)器pinMode(SensorMiddle,INPUT);//中感測(cè)器pinMode(SensorRight,INPUT);//右感測(cè)器}voidloop(){SL=digitalRead(SensorLeft);SM=digitalRead(SensorMiddle);SR=digitalRead(SensorRight);SL=digitalRead(SensorLeft);SM=digitalRead(SensorMiddle);SR=digitalRead(SensorRight);if(SM==HIGH){if(SR==LOW&SL==HIGH)//向左{left(1);stopp(2);}elseif(SL==LOW&SR==HIGH){right(1);stopp(2);}elseif(SL==HIGH&SR==HIGH){if(count<des-1){advance(1);stopp(50);}count=count+1;if(count==des-1){le(12)；SL=digitalRead(SensorLeft);SM=digitalRead(SensorMiddle);SR=digitalRead(SensorRight);}elseif(count>=des){digitalWrite(MotorRight1,LOW);digitalWrite(MotorRight2,LOW);digitalWrite(MotorLeft1,LOW);digitalWrite(MotorLeft2,LOW);delay(50000);}elseadvance(2);}else//直進(jìn){advance(1);}}if(SM==LOW){if(SR==LOW&SL==HIGH){left(1);stopp(2);}elseif(SL==LOW&SR==HIGH){right(1);stopp(2);}}if((SL==LOW&SR==LOW&SM==LOW)){le(1);}}}4.2紅外模塊程序longadvence=0x00FF629D;longback=0x00FFA857;longstopp=0x00FF02FD;longleft=0x00FF22DD;longright=0x00FFC23D;IRrecvirrecv(RECV_PIN);decode_resultsresults;voiddump(decode_results*results){intcount=results->rawlen;if(results->decode_type==UNKNOWN){Serial.println("Couldnotdecodemessage");}else{if(results->decod_type==NEC)Serial.print("DecodedNEC:");}elseif(results->decode_type==SONY){Serial.print("DecodedSONY:");}elseif(results->decode_type==RC5){Serial.print("DecodedRC5:");}elseif(results->decode_type==RC6){Serial.print("DecodedRC6:");}Serial.print(results->value,HEX)Serial.print("(");Serial.print(resuls->bits,DEC);Serial.println("bits)");}Serial.print("Raw(");Serial.print(count,DEC);Serial.print("):");for(inti=0;i<count;i++){if((i%2)==1)Serial.print(results->rawbuf[i]*USECPERTICK,DEC);}else{Serial.print(-(int)results->rawbuf[i]*USECPERTICK,DEC);}Serial.print("");}Serial.println("");}voidsetup(){Serial.begin(9600);irrecv.enableIRIn();//Startthereceiver}inton=0;unsignedlonglast=millis();void(loop){i(irrecv.decode(&results))}if(millis()-last>250){on=!on;digitalWrite(13,on?HIGH:LOW);dump(&result)if(results.value==?){}}}4.3避碰模塊程序主程序voidloop(){myservo.write(90);//測(cè)量detection();//測(cè)量角度if(directionn==2)//如果directionn(方向)=2(倒車(chē)){back(5);//倒退stopp();//停止while(1);}if(directionn==8){advance(2);}}五、綜合設(shè)計(jì)與調(diào)試5.1流程圖開(kāi)始開(kāi)始紅外信號(hào)紅外信號(hào)障礙物障礙物途徑1途徑1途徑2途徑2終點(diǎn)終點(diǎn)終點(diǎn)終點(diǎn)開(kāi)始開(kāi)始5.2軟件設(shè)計(jì)#include<IRremote.h>#include<Servo.h>intRECV_PIN=12;intMotorRight1=8;//IN1intMotorRight2=9;//IN2intMotorLeft1=7;//IN4intMotorLeft2=6;//IN3intspeedpin=11;intspeedpin1=10;constintSensorLeft=2;constintSensorMiddle=4;constintSensorRight=5;intSL;intSM;intSR;intinputPin=A0;intoutputPin=A1；intFspeedd=0;intdirectionn=0;Servomyservo;intdelay_time=250;intFgo=8;intBgo=2;intcount=0;intdes=0;intf=0;//******紅外控制部分********longadvence=0x00FF629D;longb=0x00FFA857;longs=0x00FF02FD;longl=0x00FF22DD;longr=0x00FFC23D;IRrecvirrecv(RECV_PIN);decode_resultsresults;voiddump(decode_results*results){intcount=results->rawlen;if(results->decode_type==UNKNOWN){Serial.println("Couldnotdecodemessage");}else{if(results->decode_type==NEC){Serial.print("DecodedNEC:");}elseif(results->decode_type==SONY){Serial.print("DecodedSONY:");}elseifresults->
