📃 움직이는 물체가 감지되면 LED를 번갈아가면서 켜기

// C++ code
//
void setup()
{
  pinMode(7, INPUT);
  pinMode(11, OUTPUT);
  pinMode(12, OUTPUT);
  pinMode(13, OUTPUT);

}

void loop()
{
  int readVal = digitalRead(7);
  if(readVal == HIGH) {
    digitalWrite(13, HIGH);
    digitalWrite(12, LOW);
    digitalWrite(11, LOW);
    delay(1000);
    
    digitalWrite(13, LOW);
    digitalWrite(12, HIGH);
    digitalWrite(11, LOW);
    delay(1000);
    
    digitalWrite(13, LOW);
    digitalWrite(12, LOW);
    digitalWrite(11, HIGH);
    delay(1000);
  }
  else {
    digitalWrite(13, LOW);
    digitalWrite(12, LOW);
    digitalWrite(11, LOW);
  }
}

📃 분압기 이용

// C++ code
//
void setup()
{
  Serial.begin(9600);
}

void loop()
{
  int readValue = analogRead(A0);
  delay(500);
  Serial.println(readValue);
}

📃 가변저항으로 LED 밝기 조절

20 / 1023

// C++ code
//
void setup()
{
  Serial.begin(9600);
}

void loop()
{
  int readValue = analogRead(A0);
  delay(500);
  Serial.println(readValue);
}

📃 조도센서

▪ 빛이 많으면 전류를 적게 보내고, 빛이 적으면 전류를 많이 보낸다.

조도센서로도 LED의 빛을 조절할 수 있다.

📃 온도 센서

// C++ code
//
void setup()
{
  Serial.begin(9600);
}

void loop()
{
  int readValue = analogRead(A0); // 아날로그 신호를 측정
 
  float volt = readValue * 5.0 / 1023;

  float tempur = volt * 100.0 - 50;
  Serial.println(tempur);
}

📃 가변저항의 값으로 인한 LED 밝기 변경

// C++ code
//
void setup()
{
  Serial.begin(9600);
}

void loop()
{
  int readValue = analogRead(A0);
  
  // map() 함수를 이용해 입력 값의 범위를 변경
  int convertedValue = map(readValue, 0, 1023, 0, 255);
  analogWrite(9, convertedValue);
  
  
  // 시리얼 모니터로 가변저항의 값과 범위 변경된 값을 출력
  Serial.print(readValue);
  Serial.print("\t");
  Serial.println(convertedValue);
}

📃 LCD

// C++ code
//


#include <LiquidCrystal.h>

int seconds = 0;

LiquidCrystal lcd_1(12, 11, 5, 4, 3, 2);

void setup()
{
  lcd_1.begin(16, 2); 

  lcd_1.print("ONDO");
}

void loop()
{
  int readValue = analogRead(A0);
  delay(500);
  Serial.println(readValue);
  float volt = readValue * 5.0 /1023;
  float temper = volt * 100.0 - 50;
  
   
  
  
  lcd_1.setCursor(0, 1);
  lcd_1.print(temper);
  delay(1000); 
  seconds += 1;
}
