Download the application or the source code.
Load the v7.pde file.
Set the board type: Tools -> Board -> DisplayDuino 644
Upload the program. If it doesn't work, you've probably got the wrong COM port.
Set the COM Port: Tools -> Serial Port
When the program has finished uploading, there will be a short delay and then all the gears will turn to center positions.
Quit Arduino and disconnect the power.
TIP: Never work on electronics with the power in. No one wants to let the magic smoke out.
