Ben Miller hacks a commercial pet feeder so it can be controlled remotely:
For our first project we decided to create something that would allowed my dad to feed his dogs remotely if he and my mom were out gallivanting (technical term) about. Don’t worry, the dog door allows for the post-processing to occur safely.
We did some research and found this cool project by Amanda Ghassaei: http://www.instructables.com/id/Twitter-Controlled-Pet-Feeder/
She had done a lot of the research already like finding a powered dog feeder and determining how to hack it to work on demand. Apparently, if you push the Volume and Set buttons at the same time it triggers the feed cycle. She shows how to connect to the board and use an arduino to logically push these buttons. We loved it, but wanted to add a few features
