hey guys,
i want to make an arduino robot controlled from a PC, using two 360deg. servos and an arduino uno on one side, and (most likely) processing on the other end, with usb in between for beginning/troubleshooting stages, then (maybe) switch to xbee.
i know how to control servos and most everything hardware-related, but can't find much on the software side. for example, i would like to drive with arrow keys, but can find very little documentation on this, and the code i did find didn't make sense to me.
can someone show me some simple processing code, that, for example, would light different led's on an arduino for different arrows pressed? i could definitely get a big start from that. thanks so much.
