Help with mouse input and output?

Well there's where you just stepped over the line. If you had more experience with this forum you would know that the long term contributors will completely stop helping if they think your project is illegal, immoral or dangerous.

You could have left this as a practical excercise in mouse clicking but you have now given enough information that we can be sure that you are cheating.

Please don't give up on Arduino. It's lots of fun. I'm sure you'll have a science project within the next year that you can use your experience to look like some kind of genius to the rest of your team. I am willing to help with any project except this one.
