Chienline’s DIY on making an automatic fish feeding machine is exactly that, where he combines an Arduino Uno with a floppy drive stepper motor, hard drive enclosures, an adapter and such other parts to construct an automatic fish feeding machine. <> Design goals Fish Feeder 2: No buttons on the Fish Feeder. There's heaps of info online about this but the quick and dirty reason is because the Arduino output pins are not able to supply the stepper with enough current (amps) to get the coils in the stepper to engage. We have used the 28BYJ-48 Stepper motor and the ULN2003 Driver module. While maintaining the plants or the cleanliness of the water aren’t issues when he leaves for a week, the fish still need to be fed on a regular basis. Currently there are Arduino based systems that could serve the purpose with scheduled feeding of the fish.
