Now what we've got it all wired up, we can tell the robot to move to middle position. To do that we need to load the software onto the DisplayDuino by using Arduino, which can be downloaded from MondroMatrix.The Mondomatrix version includes DisplayDuino firmware.
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.
