Now let’s put them all together and see how they work

Set up steps
1. Setup your projector properly and connect your projector to your PC computer; we recommend you fix your projector’s position, in that case you don’t have to do the calibration next time;
2. Setup your Wiimote controller and make the infrared camera size(black rectangle) points to the projective area;
Recommend the distance and position as the following:

(45 degree to the projective area)

3. Plug your Bluetooth adapter into your PC
Most of the Bluetooth adapters don’t require a driver.
(check the compatibility list for the wiimote : http://wiibrew.org/wiki/List_of_Working_Bluetooth_Devices )

Now you’ve done all the hardware’s setup!
For ceiling mounted Wiimote, we strongly recommend you to read this useful article by shaggymook .

There is a solution for how to replace wiimote’s battery with a 3v transformer! The way he handles Button 1 and 2 will save you a lot of time on wiimote connection configuration.
