KY-022 IR receiver, LED always on, no output I've been trying to use a KY-022 to read IR signals. However no output is being produced and the LED on the board is constantly on. 

Board: Arduino Uno R3

I followed the procedure found here.

The code: 

#include &lt;IRremote.h&gt;

int RECV_PIN = 11;

IRrecv irrecv(RECV_PIN);

decode_results results;

void setup() {
  Serial.begin(9600);
  // In case the interrupt driver crashes on setup, give a clue
  // to the user what's going on.
  Serial.println("Enabling IRin");
  irrecv.enableIRIn(); // Start the receiver
  Serial.println("Enabled IRin");
}

void loop() {
  if (irrecv.decode(&amp;results)) {
    Serial.println(results.value, HEX);
    irrecv.resume(); // Receive the next value
  }
  delay(100);
}


The output:

Enabling IRin
Enabled IRin


The LED is constantly on, it should come on when there's a signal received. However this is not shown in the output. :/ I don't know what to do.

The first thing to look at is the circuit board. Are they using the resistor and LED to indicate the board is receiving power? The data sheet has a schematic showing several passive components in the "3. ApplicationCircuit" section. Here is a copy of the schematic I have used that worked with the IRremote library (Version 0.1 July, 2009 - Copyright 2009 Ken Shirriff).
