Giles Booth has followed on from Matt Hawkins’ work on using a Wiimote and hooked the Bluetooth remote control device up to the Pi and made it control Turtle graphics. You can change pen colour, lift and place the pen and, of course, control the direction of the turtle. A great example of mixing software. Take a look here.
If anyone’s figured out how to permanently/repeatedly store the pairing of a Wiimote with a Raspberry Pi (i.e. without having to press 1 & 2 again every time the program is run), please do let me know.
Also, some versions of the Wiimote (notably, fakes, but some genuine ones too) pair more easily if you press the button under the battery cover, rather than the 1 & 2 buttons.
Yeah, that is a pain. I don’t know how to do it! 🙁
