IR Receiver reading only 0's

Other Hardware Sensors

Hi, I am using an IR Receiver that I've got from Elegoo super starter kit. I am also using an Arduino Uno .I've used this code to decode it to HEX format:

#include <IRremote.h>

const int RECV_PIN = 7;
IRrecv irrecv(RECV_PIN);
decode_results results;

void setup(){
  Serial.begin(9600);
  irrecv.enableIRIn();
  irrecv.blink13(true);
}

void loop(){
  if (irrecv.decode(&results)){
        Serial.println(results.value, HEX);
        irrecv.resume();
  }
}

All I get in the serial monitor (9600 baud rate) is 0. I've tried everything including checking if it was dead but it still displayed 0's. Just incase I used my 2nd IR Receiver from my Elegoo sensor kit but yet that also posted 0's. I've searched all over and use every code i could get my hands on but yet it didn't work. I've even tried using an Arduino Nano, esp8266, Elegoo Arduino Uno &, off branded Nano. I even bought more IR Receivers but they don't work ether...

I'VE FOUND A SOLUTION!

Turns out this code is a working code:

#include <IRremote.h> //Make sure to install the library
int IRpin=9;
IRrecv IR(IRpin);
decode_results cmd;
String myCom;
void setup()
{
Serial.begin(9600);
IR.enableIRIn();
}
 
void loop() {
  while (IR.decode(&cmd)==0){ 
}
Serial.println(cmd.value,HEX);
delay(1500);
IR.resume();
 
if (cmd.value==0xFF6897){
  myCom="zero";
  Serial.println(myCom); 
}
if (cmd.value==0xFFA25D){
  myCom="pwr";
  Serial.println(myCom); 
}
 
}

But I did install the wrong Library . Turns out I needed to get an older version because the newest version of this libeary is different. I downloaded the 2.2.3 version and it worked!

Here is the link to the Library you should download instead:

Or just download it directly here.

Thank you SO MUCH for this solution. I have been banging my head against the wall trying to get something beside "0". The older version of IRreceiver worked great ! ! ! ! !

The older (and newest) versions of the IRremote library are available through the IDE library manager. Always use the library manager to install libraries, if possible.
