리밋스위치 3개로 모터를 1초동안 정회전시키고
그뒤로 1초동안 역회전시키고 1초동안 정지하는 회로를 짜보았는데
저는 모터가 한번씩 움직이고 리밋스위치가 재입력될때 다시 모터가 움직이는것을 원했는데
어떻게 하는지 잘 모르겠습니다.....알려주시면 감사하겠습니다.

int Ls_1=2,Ls_2=3,Ls_3=4;
int motor_forward=5,motor_backward=6,ENA=10;
int old=0,mode=0;

void stop(){ digitalWrite(motor_forward,0); digitalWrite(motor_backward,0); }
void fwd() { digitalWrite(motor_forward,1); digitalWrite(motor_backward,0); }
void bwd() { digitalWrite(motor_forward,0); digitalWrite(motor_backward,1); }
//
void setup(){
  pinMode(ENA,OUTPUT); digitalWrite(ENA,1);
  pinMode(motor_forward,OUTPUT); pinMode(motor_backward,OUTPUT);
}

void loop(){
  if(digitalRead(Ls_1)){ if(mode!=1)mode=1; )
  if(digitalRead(Ls_2)){ if(mode!=2)mode=2; )
  if(digitalRead(Ls_3)){ if(mode!=3)mode=3; )
  //
  if(old!=mode){ old=mode;
    fwd(); delay(1000); bwd(); delay(1000); stop(); delay(1000);
  }
