is it possible to host the webpage on my computer and send the commands to the ethernet shield to tell the uno to open/close the garagedoor?Yes, that's the way I'd do it. Whether the door opening command comes from the PC or the Arduino depends how you want that to be triggered. If you intend to have somebody sat in front of the PC all day clicking the door open and closed as required, it should be initiated from the webapp. But if it's going to be triggered from a radio control/keypad/etc at the door operated by the person wanting to get in, then it would make more sense to have the Arduino controlling it directly.
Somebody else asked a similar question recently - presumably one of your classmates - so if you search out their post you might find some more hints.
The idea is to just operate it on a computer since it's just small scale and I don't have any understanding of arduino etc. yet.
Thanks for the information
