I see a few tutorials online though - I guess its a case of receiving the signal from the Wii controller so you'll need an RF receiver (not IR) the sensor bar doesnt receive data from the Wii controller, it sends it. You can disconnect the Wii sensor bar and use TV remotes, IR leds etc... instead and the Wii controller will still work. The IR bit in the controller is actually an IR camera! cool huh? Check this out: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1172459283 And: http://www.windmeadow.com/node/45 Loads of stuff already online about Arduino and Wii. Looks like you can plug the wiimote in by using the expansion port - the bit where you connect the nunchuck to the Wiimote, if you take the plug off you'll have 6 pins that you can wire into Arduino. BUT - I reckon there must be a way of receiving the RF signal from the remote which would be better. Can't think of how else the signal is sent wirelessly other than RF. Good luck! Let me know how you get on as I've yet to try doing any of this myself. Larry Hey Lorenc,

I’ve got a Wii myself but I’ve not tried working with the controllers yet.

I am using you for different things and I hope you did not get tired of this. I wanted to use some Wii object but with the mac. You think that it exist a mood to get the controller in my computer? I am trying right now but nothing happen Thank you Lorenc Hello Larry

So if you're using a different ultrasound sensor the first stage for calibration is to record the time when the echo is detected and go from there. I generally found that for large surface areas its very accurate. Larry. Hi Steve,

We are working on a way to locate water level in our educational river models and thinking of ultrasound. Specs on commercial units are all over the place--did you test accuracy on this and if so would you share? We need ~2mm precision over a range of about 100mm. Larry, great stuff, thanks for posting.

I am not able to interface the SFR05 with the software MaxMSP 5. I am trying to do it with the Arduino instructions but no way till now. If you have any idea will be great. Thank you and Merry Christmas! Hey Larry

The void loop() { is a method needed to run your Arduino code and its been commented out. Anyway I’ve updated the post to fix that.

Hope that helps.
