与最新的IRremote库不是很匹配. 特此修改如下，实验运行良好：


#include <IRremote.h>


int IR_RECEIVE_PIN = 4;

void setup()
{
   Serial.begin(9600);
   IrReceiver.begin(IR_RECEIVE_PIN, ENABLE_LED_FEEDBACK); // Start the receiver

}

void loop() {
  if (IrReceiver.decode()) {
      uint32_t tmp = IrReceiver.decodedIRData.decodedRawData;

      if (tmp != 0){
      Serial.println(tmp, HEX);
      //IrReceiver.printIRResultShort(&Serial); // optional use new print version
      }

      IrReceiver.resume(); // Enable receiving of the next value
  }
}
