Wii remote as ir signal detector
Unfortunately it's not a good idea to do that with a $40 Wii remote, designed to track the position of IR emitters, not data signals. You could do it with a &lt; $10. part such as http://www.sparkfun.com/commerce/product_info.php?products_id=8554 . See also http://www.gumbolabs.org/2010/05/29/radioshack-infrared-receiver-arduino/
