Is it necessery to use a specific frequency for the LEDs? I just want to figure out wether it is more appropriate to use DC or AC. Any ideas?


(ledcalculator.net is really helpful)

The sensor in the Wii Remote samples at 200Hz.  For good tracking, any modulation has to be at least 400Hz, and is even better at higher frequencies.  For most applications though, DC (no modulation) with a simple current limiting resistor will work best.
