2015-06-28 (Su) Automated Aerator and Laser Show for Domestic House Pets

Debugging was done for the project. Hardware used:
  • Laser module
  • Red LED in place of x-axis. PWM output results in changing intensities
  • Green LED in place of y-axis. PWM output results in changing intensities
  • Amber LED in place of pump relay.
  • Speaker
  • Button to start and stop pump show
  • Button to start and stop laser show
While debugging the program it occurred that the button should also be available to turn off each "show." This functionality was added while making the rest of the program usable. Describing debugging is not exciting since many mistakes were amateur.

A video was made of the operation. The video proves that the buttons can be used to toggle the shows for the laser and pump. Tones are audible signalling the start of a show. The video does not show that these shows will also happen at pseudo-random intervals without user input.
