This is my impulsive side when I let go of its leash. I normally go and do something crazy such as this. I got an idea while browsing through instructables. Why not build a greenhouse? I remembered a movie about an autonomous house, so why not do something like that?
I looked up instructables on greenhouses and I saw an instructables on automatic plant watering with an Arduino. That's great, I finally have a permanent use for my arduino. After brainstorming a little more I thought of using some kind of tank to hold the water, kind of like the ones they use in our city but smaller (way smaller). This would let me use gravity as my source of energy for water movement and leave no need for a water pump.
This instructable is custom for anyone, there is no exact dimensions since this is more of a "factory" of arduino workers which interoperate and keep the greenhouse in order.
I'll stop with the background/rambling and start with the steps
I forgot to mention this instructable is for the robots contest, and im 16
