DIY Cat Feeder on an Arduino

Too busy at work and can't feed your pet on the right time? Built this automated cat feeder to keep your pets happy even if they are alone at home :)


This project makes use of an archimede's screw to dispense catfood into two feeding canisters. The screw is driven by a 3.6V IKEA screwdriver motor which is controlled through a relay module. Time keeping and scheduling is done through the help of a DS1307 Real Time Clock (RTC) module. The I2C communication to the RTC and the control of the relay along with the scheduling routine is handled by an Arduino - oh wait it also has a HD77480 liquid crystal display to check the feeder's status.
