I'm new to this forum so please forgive me if I'm doing something wrong, but I need some help. I recently built an aquaponic setup and got it up and running, the issue is that it requires that the pump be on for 30 minutes and off for 30. I looked around for a device that'd let me do that, however, they're quite pricey. I then saw that my local amazon was running a nice discount on an Arduino Uno. What would I need to get to make this a machine that essentially feeds power to the pump for 30 minutes, keep it off for 30 minutes and repeat?
Thank you and have a fantastic day.
