Raspberry Pi powered fishtank


My fishtank is now internet-connected. It is run by a Raspberry Pi that can do three things: Feed the fish, switch the lights and take pictures.

To feed the fish, the Raspberry Pi sends commands to an automatic fishfeeder that I modified. It can empty any container in any order. This is achieved by an Arduino Pro Mini, two servos and a motor (more). The plate prevents hot air from flowing into the feeder.
