This is a automatic cat food dispenser. Powered by a continuous servo and controlled by an Arduino UNO board. It can be programmed to dispense cat food at different times. Both, the amount of food and the feeding times can be adjusted in the menu.
I was inspired by this project: thingiverse.com/thing:27854
