Newbie Controller Question

Hi All,

I have a few newbie questions here, sorry if this has been repeated. I took a look online here in the forums and couldn't find the answer and have been searching online but can't seem to find what I am looking for.

I am interested mostly in playing the Just Dance series of games and am wondering which controller I need to purchase. I believe I need a Wiimote with Motion Plus, but do I need the Nunchuk controller as well?

Also do I additionally need the sensor bar and what purpose does it serve? And if so can it be a generic one or does it need to be a certain brand.

I have two usb to bluetooth adapters and I guess I need these to connect the Wiimote to the computer?

Also is it possible to use an android phone as a controller?

Sorry for all the questions just having a hard time piecing all the information from different sites together.

Any help is appreciated,

Thanks

T
