(sorry if I posted this again, it didnt show on my posts and i wasnt sure if i post it or not)
I am trying to make a project where the user will make a configuration with the ir controller and then according to the settings they choose, the button wil work either as a toggle or as a push button. The configuration works fine, but the button doesnt seem to work. If i do serial.print, it outputs 0, no matter if it is pressed or not. The code for the button works, i tried it on a different sketch, the button works too and the wires are ok. Does anyone have any idea what is going on? I don't know what is wrong with the code, so I ll post anything you ask
(the code structure is : setting1-> setting2/3/4-> setting4-> button)
Thanks in advance
There is no way to figure out what is wrong with your sketch if you don't post it.
it is this that causes the issue: IrReceiver.begin(IR_RECEIVE_PIN, ENABLE_LED_FEEDBACK);
I downloaded an older library, but it had issues with the lcd.
If anyone has any recommendations on how to fix this issue I would be grateful.

here is the code, dont know if it will help since the issues is in the library

You're going to have to give us more to go on here. For a start read through How to get the best out of this forum (short version).
Then go through and comment your code so we can understand what you're trying to do and what's gong on.
Once you've done that done come back with a good description of what the problem is. At the moment we have no idea what button you talking about, how it's connected, which section of code to look at or even what library you're talking about.
if anyone has the same issue, just don't use the 3 and 11 pins, the ir controller library i used meshes up with the arduino clock
