Sorry for the late reply Sir. I will try it and post here if there's any problem.

Hi Sir,

Any NPN transistor will be fine with this IR circuit right?

Ok so, Please share Link with me, Sir. And if this doesn't work then I think there is a problem with the AC.

You need to put a delay in your Tx code at the end of the 'loop'...otherwise you will overlaod/confuse the IR reveiver in the target device. delay(5000); I will edit out the receive code you posted, as we prefer to keep one location/source for that. Ok, Sir, I will add 5-sec delay in transmitters c...

Here's the receiver's code: https://www.analysir.com/blog/2014/03/19/air-conditioners-problems-recording-long-infrared-remote-control-signals-arduino/ Here's the sender's Code: /* * IRremote: IRsendRawDemo - demonstrates sending IR codes with sendRaw * An IR LED must be connected to Arduino PWM pin...

Yes that will not give you much range. It looks like the resistor is 220R. You could change that to 100R or even 68R on a 5V Arduino. Using a transistor to drive the IR LED will increase the range a lot. There are several posts on our blog & google about this. As you said I created the same ckt...

Here's the image of the IR transmitter I am using. Ok, I will try doing IR LED close to the AC receiver.



I have tried taking it close to the AC receiver but it didn't work.

OK - I loaded the second signal you posted above into AnalysIR, which didnt recognise it at first, but once I used the 'clean' feature it then deocoded OK Here is the corrected signals: /* Automatically Generated by AnalysIR - Batch Export Utility Registered to: xxxxxxxx Session History Type : Key ...

It looks like you ran into a sie limit ith the library, which is common for AC signals. try this sketch from our blog: https://www.analysir.com/blog/2014/03/19/air-conditioners-problems-recording-long-infrared-remote-control-signals-arduino/ I have tried this. At the end, it has a receiver's code I...

Hi all, I am using IRLib2 Library to control TV and AC. My TV is working great after recording raw codes from it's remote and sending it. But my AC is not working for the same. I have a Panasonic AC and tried recording its codes it gave me this: #define RAW_DATA_LEN 100 uint16_t rawData[RAW_DATA_LEN...
