FishTimer

To cut down on fish mess I feed my fish every 48 hours. I keep mainly guppies and a big PlatCat. Scummy, the PlatCat, gets rather upset when I forget his chips every other day. And I keep forgetting if I fed them last night or not.

This project is a resettable timer. It's green when the fish are happy, yellow when they are getting hungry, red when they must be fed. Simply press the reset button on the arduino to restart the process.
