测试代码：

#include <IRremote.h>
int RECV_PIN=3; //定义引脚
IRrecv irrecv(RECV_PIN); //建立一个接受对象
decode_results results; //定义解码变量
void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600); //打开串口
  irrecv.enableIRIn(); //让定义的对象开始工作
}

void loop() {
  // put your main code here, to run repeatedly:
  if(irrecv.decode(&results)) {
    Serial.println(results.value,DEC);
    irrecv.resume();
    }
    delay(500);
}

加呼吸灯：

#include <IRremote.h>
#define RED 12
#define GREEN 11
#define BLUE 10
int RECV_PIN=3; //定义引脚
IRrecv irrecv(RECV_PIN); //建立一个接受对象
decode_results results; //定义解码变量
void Clear()
{
    analogWrite(RED,255);
    analogWrite(GREEN,255);
    analogWrite(BLUE,255);  
}
void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600); //打开串口
  pinMode(12,OUTPUT);
  pinMode(11,OUTPUT);
  pinMode(10,OUTPUT);
  irrecv.enableIRIn(); //让定义的对象开始工作
  Clear();
}

void loop() {
  // put your main code here, to run repeatedly:
  if(irrecv.decode(&results)) 
  {
      Serial.println(results.value,DEC);
      if(results.value==16738455) Clear();
      else if(results.value==16724175){ Clear();analogWrite(RED,0);}
      else if(results.value==16718055){ Clear();analogWrite(GREEN,0);}
      else if(results.value==16743045){ Clear();analogWrite(BLUE,0);}
      irrecv.resume();
  }
   
    
    //2=16718055
    //3=16743045
    //1=16724175
    //0=16738455
    delay(500);
