Plant watering system

This contains all necessary parts for a plant watering system based on Arduino Nano.
The lower "floor" contains the cogs which are needed for giving a micro-servo the torque for opening a micro-irrigation system valve.
The upper floor contains the electronics: Arduino Nano, a capacitor for the servo and (optional) cables for humidity sensor.
The water storage is adapted from Water Tower by Scott.
Arduino sketch is a simple timer for turning the servo.
