Hi TomGeorge!
thx for your interest. well I'am an interface designer. I have discovered the physical computing world for me. displaying and controlling throuh a display is really exiting. I programm quiet well in Java and I have began learning C++ . The two languages are quiet similar. After studying different Arduino books I have a good basic understanding of Arduino programming and elektronics.
As mentioned my goal is to build a larger robot, which drives remotely around by a user interface and collects sensor data. I would like to know what people are building with the Arduino, I mean larger and more complex robots. What hardware are they using?
