Building an IR controller



  • Time for a new project.

    Some time ago I build a serial gateway and a servo to control my floorheating thermostate.
    Now I want to build a device to control a media box ( switch it off via my vera 3)

    Today I have hooked up a IR reciever and transmitter on a arduino uno.
    Uploaded the sketch and tried to controll the media box.

    No , it isn't working , i think it is going wrong somewhere reading the IR-code.

    Whatever button I press on a remote , it always shows the same code , for the transmitter of the mediabox it is "000000" , for the transmitter of a Yamaha amplifier , it is "ffffff" Every button on those remotes gives the same code, that can not be right.

    Using the serial monitor this is confirmed. ( see the copy paste at the bottom of this post).

    What is wrong? and what else can I try to read to correct code?

    Thanks for the help ,

    Here the output from serial monitor:

  • No one has a clue on how to troubleshoot this?
    😩



  • @Corvl

    I don't know which IR library you are using, but this one is very good:

    https://github.com/cyborg5/IRLib

    Several examples to troubleshoot IR issues and don't forget to read the manual there (84 pages!).



  • pffff , 84 pages ..... it is something I have to read I guess .

    Thanks for the info ..... I will report here if it is working ......
