 * We've blinked an LED and controlled eight in sequence now it's time to

 * control colour. Using an RGB LED (actual 3 LEDs in a single housing) 

 * we can generate any colour our heart desires.

 * (we'll also use a few programming shortcuts to make the code

 * more portable/readable)

4. 적외선센서를 이용한 아두이노

2. 그림 설명:적외선센서에 물체를 가까이하면 붉은색 led등이 켜진다.

3. 연결방법

적외선 센서(FC-51)

VCC     -   5V

GND    -   GND

OUT     -   3~

LED                       

+          -    2

-           -   GND

3. 소스 코드

const int irDetectPin = 3; //FC-51 Pin 설정

 const int ledPin = 2; //LED Pin 설정

void setup() {

 pinMode(irDetectPin, INPUT); //FC-51 입력으로 설정

 pinMode(ledPin, OUTPUT); //LED 출력으로 설정 }

 void loop() {

 int noDetect = digitalRead(irDetectPin); //FC-51 상태 읽어오기

 if(noDetect) //FC-51포트가 HIGH이면 즉, 감지 안되었다면

 digitalWrite(ledPin, 0); //LED Off

else //LOW 즉, 감지 되었다면

 digitalWrite(ledPin, 1); //LED ON

 }

FC-51에서 나오는 값이 HIGH 이면 감지가 안되고 있다는 얘기이고

LOW 떨어지면 장애물이 감지되었다는 것이다.
