Id love to build an automated pet feeder for my cat.
Not because Im lazy (ok maybe just a bit), but there are times when Im going away for just 24 hours, and its a bit of a hassle driving 10 miles to the cattery each time.
What Im thinking is some 10 inch pvc tubing filled with tasty biccies, with some sort of servo at the bottom, and an arduino controlling timing. Every 5 hours it rotates the servo, allowing a payload of deliciousness to drop into the bowl below.
For water, its less of an issue really, since my cat isnt going to drink a full bowl of water in 24 hours. But it would be cool to do water too. Maybe a similar sort of setup with a water float gauge to allow the bowl to remain filled.
Not looking for exact instructions on how to do this, just wondering if anyone has built something similar, or has other ideas on how best to do it?
