조도 값(밝기)이 밝아짐에 따라 켜지는 LED 갯수가 많아짐 

// C++ code
//
void setup()
{
  Serial.begin(9600);
  pinMode(8, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
  pinMode(11, OUTPUT);
  pinMode(12, OUTPUT);
  
}

void loop()
{
   int A;
   A= analogRead(0);
  if(A>100){digitalWrite(8, HIGH);} else{digitalWrite(8, LOW);}
  if(A>200){digitalWrite(9, HIGH);} else{digitalWrite(9, LOW);}
  if(A>300){digitalWrite(10, HIGH);} else{digitalWrite(10, LOW);}
  if(A>400){digitalWrite(11, HIGH);} else{digitalWrite(11, LOW);}
  if(A>500){digitalWrite(12, HIGH);} else{digitalWrite(12, LOW);}
  Serial.println(A);
  
}

조도 값에 따라 7세그먼트에 표시되는 숫자가 변함

// C++ code
void CLS() { 
  for(int X=2; X<10; X++) {digitalWrite(X, LOW);} 
}

void disp(int N) {
 CLS();
 switch (N) {
  case 1 : digitalWrite(3, HIGH); digitalWrite(4, HIGH); break;
  case 2 : digitalWrite(2, HIGH); digitalWrite(3, HIGH); digitalWrite(5, HIGH); digitalWrite(6, HIGH); digitalWrite(8, HIGH); break;
  case 3 : for(int N=2; N<6; N++) { digitalWrite(N, HIGH); } digitalWrite(8, HIGH); break;
  case 4 : digitalWrite(3, HIGH); digitalWrite(4, HIGH); digitalWrite(7, HIGH); digitalWrite(8, HIGH); break;
  case 5 : digitalWrite(2, HIGH); digitalWrite(4, HIGH); digitalWrite(5, HIGH); digitalWrite(7, HIGH); digitalWrite(8, HIGH); break;
  case 6 : digitalWrite(2, HIGH);  for(int N=4; N<9; N++) { digitalWrite(N, HIGH); } break;
  case 7 : for(int N=2; N<5; N++) { digitalWrite(N, HIGH); } break;
  case 8 : for(int N=2; N<9; N++) { digitalWrite(N, HIGH); } break;
  case 9 : for(int N=2; N<6; N++) { digitalWrite(N, HIGH); } digitalWrite(7, HIGH); digitalWrite(8, HIGH); break;
  case 0 : for(int N=2; N<8; N++) { digitalWrite(N, HIGH); } break; break;
 }
