IR receiver hot

I have my IR receiver wired as attached. When I have power running through the board, the receiver becomes very hot.

OP’s picture:


What code is running on that board?

Most likely, the receiver is wired backwards and now destroyed. It may take the Arduino with it.

Post a link to the receiver module, after reading and following the directions in the "How to use this forum" post.

#include <IRremote.h>

const int RECV_PIN = 9;
IRrecv irrecv(RECV_PIN);
decode_results results;

void setup(){

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

I see you did not bother to read the "How to use this forum" post, or post a link to the module.

That is an outstanding approach to getting help!

I have read the "How to use this forum". I don't know what the link to the module is.

A link to the module. Like a hyperlink that I can click on and go to some webpage and find out what module you actually have. It's really hard to work on things when people hide all the details.

If you read the How to use this forum thread then why are you ignoring the forum rules about posting code? Where are your code tags? Go read it again please.


I don't know what the link to the module is.

Perhaps start from the beginning. How did you acquire this module?

When you say module, do you mean the type of Arduino board? If so, I have an Arduino Uno and I got it from my professor for the class.


I had someone help and I got it working thank you though

Although I thought the picture would be enough because that is the type of receiver I have. Don't have a link to it.

The point is, you did not ever provide a picture of the IR receiver.

You did at one point, show a Fritzing diagram of something or other.

So someone helped you to put the connections round the right way.
