Thanks. The purpose of the 3v and ground feeds D2 as a toggle between scrolling the text and a static text display. I have a few phrases that were too long to fit on the 8 tiles, so I have an external relay control that puts 3v on D2 to start the scrolling and when the 3v goes away it's a static phrase.
Good luck, send me pics when done.
This is really cool. My wife loves dragonflies and my daughter is starting to get involved with Arduino. When I show this to my daughter she and I will be making one for my wife!!! Thanks for sharing.
