how to read ir signal with arduino

Question

Arduino

We have the following scheme: Arduino, IR signal receiver
I want to implement the following functionality: Reading the IR signal from the remote control of the IDEA air conditioner and transmitting it using arduino. .
When trying to set up the equipment, the following problem arises: Using the IRemote library, I read the IR signal from the remote control of the IDEA air conditioner. I receive an unknown signal in RAW format (100). Making changes to the IRemote library. In the IRemote H file, I change the data: in the define RAWBUF 100 // Length of raw duration buffer line, I change the number 100 to 255. However, when I read it again, the same RAW (100) signal comes. I'm trying to send a signal from arduino to the air conditioner, the latter does not respond. The frequency of the transmitted signal is 38.
(Anthological circuit reads IR signals from TV remotes, LG air conditioners, DVD) Tell me how to correctly read and transmit an IR signal using arduino. Thank you.

Answer 1

- are you sure that the IRemote library correctly recognizes the remote control signals, and that this is exactly the protocol?
- are you sure that you can take and change RAWBUF to 255 like this, and that the air conditioner will perceive it ??
- how do you transfer the signal from the arduino back to the air conditioner ??

Please look at this article " Simple universal IR remote control decoder " Perhaps this is what you need
