Wiimote Glovepie projects / GlovePie help
« on: October 22, 2008, 07:51:35 PM »
sorry i am new to this program, i nid a little help here.

Basically i start writing my own script, i found out that when i try to detect the movement of the wiimote using infrared, i wont be able to use the nunchuk. For some reason, the nunchuk cannot be detected unless a second script started to run. Even though doing this can solve the nunchuk connection, but it wont be able to detect wiimote movement using infrared.

I wonder who gt this problem and already solve it. If so, can kindly tell me the solution or possible explain it thx a million :)

heard this before, i think they create one interesting whiteboard with lots of interesting function. If they could make it smaller and portable to carry it would be best!
