Cat Food Dispenser
thingiverse
This automatic cat feeder features a continuous servo powered by an Arduino UNO board for programmable food dispensing. Adjustable feeding times and food portions are set through the menu. Inspired by a Thingiverse project, it 3D prints parts with PLA and a 0.3mm layer height; support material is only necessary for the housing's bottom part. A T-shaped waste pipe and an extruder screw (downloadable here) comprise the dispenser, while a food container sits atop. M3 screws in varying lengths are required, along with an Arduino UNO board, LCD/keypad shield, RTC module, continuous rotation servo, and 6-12V power supply. My source code is available for download, though improvements may be made; comments might be unreadable due to my non-native English proficiency.
