Trouble Shooting - IR Pen is it working?

This is a great, simple method to see if your IR pen is actually working. Our eyes can't see the light beaming out of the pen. Your wiimote is clever enough to see the pen blinking away when you click the button on the pen. If you have a digital camera, or a cell phone with a camera then simply switch the device on and point your IR pen directly at the camera. Click the button on the side of the pen and look through the view finder of your camera. If your IR pen is working then you'll see the end of the pen lighting up like a christmas tree!
Ideally the stronger the light, the better the pen will work for you.
This is also a great way of checking out any of your tv remote controls which haven't been working properly recently.
