I thought this might be useful information if anyone else is looking to use just their Open Pandora device to program, compile and upload to their Arduino device.
(I have specifically built/coded for the Duemilanove, but with a few minor mods you could port this to other variants)
http://boards.openpandora.org/index.php?/topic/5184-arduino/#entry165715I've uploaded a youtube video (link at end of above post), to demonstrate the C code, running make and the uploading to the Arduino itself and then the infamous flashing led doing it's thing.
I searched for quite sometime without finding any help/guidance on how to get these two devices to work together and now that I've got them to work, I thought I'd share to help anyone else out on this journey.
