I am looking for a guide or advice to help get started on automating valves (for flow rate adjustment and emptying tanks) on my aquaponics system. I have an arduino uno board and looking to utilize it for this purpose. My programming ability is amateur at best, but I am a fast learner. My first goal is to use a solenoid valve to empty a swirl filter on a daily basis.
I am hoping for schematics to wire a solenoid valve to the arduino and some sample code to get started on programming.
There is a lot of good material on instructables.com. Try searching google for garduino, gardening + Arduino.
Arduino code is pretty basic. There are some great tutorials on the web but it can be difficult to figure out were to start. I found the Vilros Starter Kit to provide a good introduction. It is $55 on Amazon and comes with some components. I really like the tray that a bread board and Arduino can attach to, it makes developing so much easier.
For my project I ended up going for a small half amp pump since my goal was to have everything run off of a solar panel.
Also if you are working with water there is a quick and dirty moisture sensor that you can use to detect a leak and shut things down. Among other things this link has instruction for making the sensor and the code.
Working through the modules help build a little confidence, but the guide and code comments lacked a sufficient explanation for my low level. I'll check out your link.
Running a solar power system sounds like where it's at. Kudos! I hope to be experimenting with that soon. I thought about a DC pump that can be adjusted, but I worry about it loosing power and having to occasionally tune it to meet a constant flow rate. I have found some valves that will self adjust. Haven't tried them yet. But I will share the results.
To be continued...

Thanks Allen. Looking forward to exploring the topics.
