Millam hacked an automatic feeder with the help of an Arduino set to respond when a little wiffle ball was dropped into a bowl.

This fish feeder is based on an Arduino Uno, the 8-bit microcontroller development board which has done so much for so many.

Using the ever-popular Arduino Uno, the feeder is connected to a platform that uses load cells to detect the pet’s weight. The weight data is then used to identify which animal is looking for food.

You could ask your neighbor to feed your pet or you could construct this DIY feeder that’s activated by Twitter posts. The project is Arduino based and uses the Arduino Ethernet shield to respond to ...

You can make a pretty easy automatic feeder using a glue stick, cardboard, a continuous-rotation servo, and an Arduino to control the servo.

Building Arduino projects can be a lot of fun, but building your very own Arduino robotic pet takes it to the next level, check out the new Arduino powered Seek N' Sneak 2 kit below.
