Fab - Arduino for Visual Studio said… - Your project is really cool. I have a question but not about ipod. I am building a ground station application for arduino and like your attitude icon/picture.
Where did you get the picture? did you make it yourself? do you have any others? do you have your attirude icon as seperate images png/bmp.
Thanks, I hope you don't mind my questions
