UFF – a.k.a Unmanned Fish Feeder

Few people these days at the lab. Only our new two fish members stay at the water tank, and need to eat! Fortunately arduino is here to make things easy. This is a home-made, arduino-powered fish feeding device:

Home-made Fish Feeder

A pot containing delicious fish food is attached to a small SG90 servo that makes it turn. The screw top (here upside down) is fixed, and the screw has been removed. It also has a little hole with a flap that helps the food leaving the pot when the pot turns. The servo is connected to an arduino that moves it between two pre-defined positions during a short time, and then waits for 12 hours until the next meal 😉

Hopefully this will keep our underwater friends well fed during August…
