Make an automatic fish feeder with Arduino Uno. via instructables
In this Instructables I’m going to show you how to build an Automatic Fish Food Feeder. So you don’t have to remember to feed your fish daily because your Arduino will do it for you. You can also set timers at which the fish get fed automatically like ever 6 hours or so.
This is exclusively for those beginners who want to have the knowledge of Servo motors and Arduino. This is very simple to construct and no soldering skills are required.
