I had a problem with my LeBistro Petmate automatic feeder. The microcontroller blew an input pin and there were no replacement parts available. Having recently discovered Arduino I decided to try to run it off the Arduino. I offer up here a sketch and set of photos for anyone else who wants to do this. This is a simple solution that just runs one scoop every 12 hours. It is easy to modify the timing and servings in the sketch, but this is not elaborate. It does not drive the original LCD and has no "clock". The timing starts when you reset the micro.
Anyway, just in case it helps anyone here is a zip file with a few pictures and the .ino file:
