    Hey guys,

    I am trying to build a simple Wii remote peripheral for a project. I want to wire this potentiometer (http://search.digikey.com/us/en/products/EVW-AE4001B14/P12426CT-ND/637165) to the I2C bus port on the back of the wii remote. It will read data from a trigger of a wii-mote attachment I am working with. This port should read analog data because the wii nunchuk has an analog stick. I am trying to get the wii remote to interpret the pot's reading as it would interpret a single axis from the nunchuk's analog stick.

    I am using Darwiin Remote to observe data from the wii remote graphically on my computer.

    My problem is that I'm not sure what chip (if any) I would be best using for this. I've got an old nunchuk that I can use but that chip will handle so much more (two pots, an accelerometer, two buttons) than I need, there must be a simpler way to do it.

    Anybody have any thoughts or ideas?

    here are specs on the I2C bus port:

    Hi muse7789!

    The PCF8591 is a popular A/D converter. You can connect your pot(s) analog or accelerometers on it. With voltage dividers it can also be used for switches. Sure you need a piece of code. Maybe Darwiin Remote have a list of supported I2C devices, if so just tell us and I will have a look on.
