IR Receiver Help

Hello all,

I need help with my IR receiver. I have a code to drive a 'car' with a TV remote. I know the code is fine and the library is fine because it was working fine yesterday but now it wont work. I have also tried a sample code that I know works but no luck.

Instead of the small led on the receiver staying off and flashing when receiving a signal it just stays on.
It also doesn't print to the serial monitor anymore.

Is the chip fried? I would think it would do the opposite if it was fried (ie. no led flash)

I only have the one receiver so I can't double check the code either but I'm positive it isn't the issue.

Any help is appreciated.


Without your code and a connection diagram we cannot help.

Please put your code in its own window as seen in other posts. This can be done by placing     [code]  and [/code]  around the code or use the </> icon. This makes it easier for others to read.

How to use this forum


The code I was trying to test it with is from the Arduino starter kit.

#include <IRremote.h>
#include <IRremoteInt.h>

const int irReceiverPin = 7;  
const int ledPin = 13;
IRrecv irrecv(irReceiverPin); 
decode_results results;    
void setup()
void loop() 
  if (irrecv.decode(&results))
    Serial.print("irCode: ");            
    Serial.print(results.value, HEX); 
    Serial.print(",  bits: ");           
  if(results.value == 0x6D0)

Your sketch works perfectly.

You either have a wiring problem or you have damaged your hardware.
Often breadboard wires can be open/intermittent.
