Greetings all. Need help getting my Arduino UNO (R3) to talk to my satellite tracking program ( GNOME Predict ) for amateur radio satellites. Looking to drive 2 servo motors to move antennas. New here, new to Arduino, and yes I did buy the books and slowly learning. Running Pinguy OS ( Linux distro. ) but would like to also try Win XP. Many thanks for any and all help. 73 Ben
