2015-06-26 (F) Automated Aerator and Laser Show for Domestic House Pets

The intention of this device was to periodically start a water pump which provides bubbles which are entertaining to my cat and a pseudo-randomly moving laser dot which are entertaining to many cats.

My cat pondering her paw

Pseudo-code was translated to code for the Arduino. Some small errors and corrections were made. According to the first draft of the code the two functions couldn't run at the same time. So, if the laser show was running the pump could not start and if the pump was already running the laser couldn't start. This should be the case when the periodic timers expire but if the user presses the buttons sequentially there shouldn't be any reason both cannot run at the same time. The code compiled after some minor debugging and it was downloaded to an Arduino Duemilinove but not tested in hardware.

To Do:
  • Write code
  • Program Arduino

  • Buy mirror
  • Design structure and explain
  • Write instructions
    • Make a linkable parts list
    • Draw schematic
