My girlfriend has a cute little dog and an obsession with novelty feeding devices, aka enrichment feeding toys. There are many of them spread all around the house and it was only a matter of time until she needed an automated food timer.
What a great opportunity to make good use of a Microcontroller to make a (hopefully) cheaper custom feeder, instead of buying yet another commercial product.
