I have yet to purchase an Arduino. I have used stamps and Coridum AVR before. My question is for debugging do I need to use a separate serial connection to the board or does it update the serial monitor over the usb?
Thanks :o
Comes up via usb. No extra cable nedded. Just click serial Monitor in the IDE and up pops a window.
Note that arduino does does not particularly support "debugging" in the modern sense.
Serial.print output does show up over the same serial/usb port used for firmware upload (overall, I think it ends up about the same as Stamp?) (Become a fan of "printf style debugging" on facebook!)
