IntroductionThis is a port of Johnny Chung Lee's Whiteboard app for the actual Wii. Kudos & thanks to Johnny Lee, Team Twiizers, svpe, shagku and para. What you needTo use this application, you need the following:
How to use the applicationPlease see this video for an introduction: http://www.youtube.com/watch?v=MOa3HHblfEg What to do if something doesn't workUse a LED with a large opening angleIR LEDs vary in many things. One of them is their opening angle. As you can see in the video, I'm holding my pen kind of sideways. That is because my LED only has a 90° opening angle. So if I point it directly to the screen, all the light will go to the screen and none to the Wiimote. Try to get an LED with as large an opening angle as possible. Make sure your LED gets enough voltageAnother reason can be that the Wiiimote doesn't get enough voltage. Most LEDs require 1.3V-1.5V. A rechargeable battery only outputs 1.2V! Use a "real" battery, which outputs 1.5V when full. Due to the resistance of the wires, you will still not get the entire 1.5V to the LED. It should be enough, but if it isn't, you can use two batteries in a row. This will result in 2.4V if you use rechargeable batteries or 3V wiith regular batteries. That is too much for the LED, but it will still work for a while (especially since the LED is only on for small amounts of time). |

A simple tv remote seems to work fine here, as long as you aim for the wiimote. Good enough for testing this program anyway.
Nice work!
@azeazezar: Good idea! Probably depends on the remote's modulation rate, though; if that is too low, you'd get lots of on/off cycles when you hold down one button.
