Technical How To’s

This tutorial will show you how to use your Wiimote as a mouse on your Windows PC with IR functionality.

Hardware you will need:

• Bluetooth adapter
• Wiimote
• Wii Sensor Bar
• Windows PC
• Wii

Software you will need:

• Kensington WIDCOMM Bluetooth stack
• Bluetooth adapter drivers
• GlovePIE by Carl Kenner

In order to use your Wiimote as a mouse on your PC, you will have to connect it to the PC via Bluetooth, then run a script in the GlovePIE application that will translate the Wiimote actions to mouse actions. For this tutorial I will be using the Anycom 200 Bluetooth adapter which I got for $7.28 shipped from Buy.com using Google Checkout. NOTE: Microsoft’s Bluetooth stack will not.

Connect Wiimote to PC:

1. Download, extract, and install Kensington WIDCOMM Bluetooth stack. (Run Setup.exe)
   NOTE: DO NOT plug in adapter during installation when asked
2. Plug in adapter
3. When asked to install drivers, insert CD that came with adapter and continue installation
4. Open My Bluetooth Places to start the Initial Bluetooth Configuration Wizard
5. Press the Next button until you ge to the Bluetooth Device Selection screen
6. Press the red SYNC button under the battery cover on the Wiimote (LEDs on the Wiimote should blink)
7. Press Search Again in the wizard
8. Nintendo RVL-CNT-01 should appear
9. Select it and press Next
10. Skip Pairing
11. Make sure the LEDs on the Wiimote are blinking (press the red SYNC button again if you have to)
12. Press Refresh in the wizard if necessary
13. Check the box next to Nintendo RVL-CNT-01 and press Next
14. Press Skip the Next
15. Reopen My Bluetooth Places
16. Select Bluetooth Setup Wizard from left panel
17. Select I want to find a specific Bluetooth device… and press Next
18. Select Nintendo RVL-CNT-01 and press Next, if it is not there repeat steps 6-8
19. Repeat steps 10-13
20. The icon shown for Nintendo RVL-CNT-01 when View devices in range is selected should now have a green connection symbol on it, if not repeat until it does

Use Wiimote as mouse:

1. Download and extract GlovePIE
2. Run GlovePIE.exe
3. Select File->Open
4. Open file named TestWiimote.PIE
5. Press Run
   NOTE: if numbers do not change, you Wiimote is not connected to your PC properly
6. Press Stop
7. Turn your Wii on and make sure the sensor bar is over or under your monitor
8. Select File->New
9. Cut and Paste the following script into the window and press Run:

//Calibration:
//To calibrate, run this program and put the Wiimote on a flat surface face-up.
//Then read the values in the debug line (next to the run button).
//Change these values until the debug line reads approx. all zeros.

//Options:

//to make it easier to click. Higher = smoother but less accurate.

var.rumble = false //makes the wiimote rumble if you hit the edge of the screen
//more options to be added later

//Point Wiimote = Move Mouse
//D-Pad = Arrow Keys

Script provided by vkapadia.

You should now be able to successfully point and click on your PC just as you would with a mouse.

You will have to repeat steps 15-20 of Connect Wiimote to PC above, each time you want to reconnect to the Wiimote.

The script provided requires a sensor bar. You can create your own or modify the one provided with the Wii to be powered from batteries, eliminating the need for the Wii to be powered on. Also, you can use 2 lit candles placed near the bottom of your monitor but I don’t recommend this.
