Can someone kindly describe to me in words and at a high level the methodology used here because I find the Arduino code very hard to follow because there are so few comments.So what I mean by this is does he shift in the first bit of the first row of the first word and then clock through all the rows etc. I.e how are the columns and rows clocked such that persistence of vision works? Or is there some similar code that I can look at that is well commented?Thanks you

The first one I built has been running for years with no leaks. The pressure is really low with this little pump. So I'd say the probability of a leak is low. The electric motor on the other hand needs to be protected from the weather. It would not last long outside of the protection of the enclosure.

Thanks Dave. Wow that's quite a list! I I'll look at incorporating these if I do another improved one. I especially like the idea of a dry reservoir alert and soil moisture measurement.Simon

I agree. I'm thinking about developing it further and making it solar powered. If I do that, then I'll probably do a proper PCI.

Yeah thanks for the encouragement. The parts are so small I can't even see them very well without a magnifying glass! Anyway I'll play around with it some rainy day...

Hi Vadim, Congratulations on an excellent project, thanks for posting. Would you or anyone else that understands it be able to post the Arduino code with full explanatory comments? Or an explanation of how the code works? For the Arduino beginner the program is very hard to understand. I would like to build something like this but without understanding the program, there is not a lot of point, because like anyone my objective is to completely understand how it works.Thank you for any help.Regardssimon
