Updated WiiController library
!!!DOES NOT WORK WITH NUNCHUCK!!!
If you are using the adapter in this link,http://www.ebay.com/itm/Wii-WiiChuck-Nunchuck-Adapter-Module-Board-for-Arduino-/351052353286?pt=LH_DefaultDomain_0&hash=item51bc59cf06
then you most likely have it plug into the arduino across pins A2 - A5. Please know that the controller needs 3.3V to work properly and NOT 5V. You may cause possible
to the controller if it is powered by 5 volts. What I have done here is allowed the user to use pin A2 as ground, by setting the pin to LOW, and making pin A3 an input
so the user can have a jumper to the 3.3V pin without harming the Arduino.
**.begin(Vcc, Gnd)**
Vcc: Set to ON if you are using the adapter AND the Arduino board you are using outputs 3.3V. (Like a Pro Micro or DUE)
Vcc: Set to NEUTRAL if you are using your own wires and are not using pin A3 for power. (pin will be set to INPUT)
Gnd: Set to OFF if you have the adapter in the pin A2, this will automatically set pin A2 to LOW. Otherwise leave empty, default is OFF
