+Example sketch for the Wii libary showing the IR camera functionality. This example

+To test the Wiimote IR camera, you will need access to an IR source. Sunlight will work but is not ideal.
+The simpleist solution is to use the Wii sensor bar, i.e. emitter bar, supplied by the Wii system.
+Otherwise, wire up a IR LED yourself.
