I have these 3 things at hand:
I would like to build myself an automatic plant watering apparatus. I looked up a diversity of youtube videos and websites. But either they show only the end results or talk how they achieved it without showing any steps. But before I jump in and kill myself with electricity or drown in the water, I would like to know if it is possible to achieve an functioning automatic plant waterer by my self. If yes, then what parts do I also need?
