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.
