int URECHO=3; // PWM Output 0－25000US，Every 50US represent 1cm
unsigned int x=0;
uint8_t EnPwmCmd[4]={0x44,0x02,0xaa,0xf0}; // distance measure command
//
void setup(){
Serial.begin(9600);
AutonomousMode_Setup();
}
//
void loop(){
AutonomousMode();
delay(100);
}
//
void AutonomousMode_Setup(){ // PWM mode setup function
pinMode(URECHO,INPUT); // Sending Enable PWM mode command
for(int i=0;i<4;i++)Serial.write(EnPwmCmd[i]);
}
//
void AutonomousMode(){
unsigned long DistanceMeasured=pulseIn(URECHO,LOW);
if(DistanceMeasured>=45000){ // the reading is invalid.
Serial.print("Invalid");
}
else{
x=DistanceMeasured/50; // every 50us low level stands for 1cm
Serial.print("Distance="); Serial.print(x); Serial.println("cm");
if(x>180){ 흰색ON; 적색OFF; } // 흰색 점등
else { 흰색OFF; 적색ON; } // 빨간색 점등
}
}
흰색과 적색 LED는 핀 설정하고 출력하는 코드를 추가하시고요

}
}
1초 점등을 1회만 하는 코드는 이렇게 작성하면 됩니다.
180cm 이하에서 1회만 적색1초 점등후 OFF
180cm 이상이 되면 flag 초기화
