Cat Food Dispenser

thingiverse

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: http://www.thingiverse.com/thing:27854 Thanks, kitlaan A video of the food dispenser work can be found here: http://youtu.be/rjNdQmLi_hw Instructions 3D print: All parts are printed with PLA and a layer height of 0.3 mm. For the bottom part of the housing you need support material. All the other parts can be printed without support. Hardware: For the dispenser itself I used a T-shaped waste pipe (found a the local hardware store) and a extruder screw which you can be downloaded here: http://www.thingiverse.com/download:83004 On top of the dispenser you need to put a food container (I will add a photo of mine soon). You also need some screws in different lengths - all M3. Electronics: Arduino UNO board (http://arduino.cc/en/Main/ArduinoBoardUno). This is the brain of the food dispenser ;-) LCD / Keypad shield similar to this one http://www.hobbytronics.co.uk/arduino-lcd-keypad-shield RTC (real time clock) which is simular to this one http://www.hobbytronics.co.uk/real-time-clock-module-ds1302?keyword=RTC Continuous Rotation Servo like this one http://www.hobbytronics.co.uk/springrc-sm-s4303r?keyword=servo Power supply (6 to 12 volts). Program: You can download my source code for the arduino board, but be aware that I just started my programmer carrier. I assume that there are many things to improve ;-) Due to the fact, that my mother tongue is german, there might some comments in the code you can't read ...
