Ok, I"m in the planing stages of my first arduino project.
I'm going to make a web controlled web cam (pan/tilt via web)
I was going to use a the ethernet shield and a web server to interact with the arduino,
tonight i've been reading about communicating with the arduino directly with PHP and the serial port.
why would one use the ethernet shield when they can just use the serial port.
the only reason i can think of is, you don't want to have the arduino right next(usb length) to the PC, am I missing anything?
is there a bottleneck with the serial port over the ethernet shield?
