    Hey,

    I wanna try to decode the buttons of my TV remote control, but for that I will need an IR receptor, which currently I don't have. Except for a strange little piece I found on my home today which apparently has a TSOP integrated to it on one side and the other side has a P2 output. I got no idea what's the use of that.

    This one:

    But I was wondering... can I still use it somehow? Any ideas?

    Whoops... I used the wrong word right there, my bad. I meant a P2 output, exactly like the ones found on headphones cables.

    P.S.: Is it possible to edit threads?

    that didn't really help
    What is a P2 outlet ??

    yes it is but for a limited time after the post ... cant remember exactly .. several hours

    I will edit you thread for you ... but you still need to clarify the P2 thing
    in 45 yrs of electronics, I have never heard of such a description

    Ok, I can't find a way to be clearer than that. So here goes: this is the P2 plug/jack I mentioned.

    OK no probs, as I said, I have never heard them referred to as that. They are just a standard 4 contact, 3.5 mm TRRS connector.
    out of curiosity, where did you hear the P2 naming ?

    Depends on your skill level and whether it contains an infrared sensor. Most remotes (except Bluetooth) use pulse-width modulated infrared transmitters. If you have an oscilloscope you can "see" these "codes" with just about any IR photo-diode. Amplifying and decoding the pulse trains is a whole 'nother matter. You can buy modules that will do this for you, and the thingy you have may include such a module, which would explain why it has a 4-wire connection to the phone plug you are calling a P2 (whatever that is).

    Much more information is needed. How advanced is your electronics capability? Have you built circuits "from scratch" using discrete components? What kind of test equipment do you have? Answer these questions and we will be able to offer better advice.

    Well, we use this denomination all the time here in Brazil. I thought it was valid worldwide.

    I'm a beginner in electronics. I started using microcontrollers (Arduino) very recently and never built a circuit outta scratch. All I wanted was a TSOP (a photoreceptor) with connections to one of the Arduino's digital pins, another to the power source (5v) and the other to ground. How can I make that "thingy", the TRRS connector (thanks, davenn) work combined with my board?
