I suck at taking care of plants. So I made a plant that would feed itself by using an arduino, a moisture sensor, and a water pump.
The moisture sensors in the soil detect the water moisture level. Once it detects that it's dry, it tells the arduino to turn on the water pump and feed water into the plant.
To cover up the ugly hose, I've gave the plant its' own mini-cloud to make it look like it is raining on top of itself.
