Arduino Nano - IRremote - pin out set on D0 (RX) [FIXED]

Using Arduino Programming Questions
1

I've got a problem with IRremote and arduino Nano.
I try to find a solution online, but it seems I'm the only with this problem.

IRremote is supposed to use the pin 9 (or 6 or 3) for the output, but in my case after several attempts I found the library use the pin D0 (RX) for the output.

This is a problem, because it works fine, but I've to disconnect the led to program the board.

There is a way to change the output PIN of IRremote for Nano?

Are you using a classic Arduino Nano one one of the exotic newer 'Nano' models like the "33 BLE" or the "Nano Every"?

I use a classic Nano...is not original, but it works fine with everything else.
I try to test all the pins with an oscilloscope, but only the RX0 pin has a signal output on it.

The circuit is really simple: only the board and only 1 IR led (with resistance)....but even only board does works only on RX0 pin.

The default send pin for a Nano with the IRremote library is pin 3. You should be able to change it with:
#define IR_SEND_PIN x // where x is the pin number to use for sending

The above must be before the #include <IRremote.hpp> line to take effect.

See the GitHub page for the IRremote library.

EUREKA!!!
it does works!!!

thanks a lot.
How can I flag it as "fixed"?

Actually I notice that when I load the script, IDE give me this message....but it does not set it as an error.

See the IRremote GitHub page for how to fix code written for older versions (< 3.0) of the library.
