Arduino Automatic Watering System
DESCRIPTION
First of hopefully many DIY arduino projects. I will show you how to build an automatic watering system. It will water plants for you when you not there. Although project is based on Arduino Nano there is no problem to build it with Arduino UNO.
Watch whole video. It will take you through nearly the whole project. You will find additional resources in the following steps.
These are necessary parts and sample links where to get them.

See attached schematics and pictures of assembled boards. If you are not comfortable with soldering build just breadboard version of the project.
Upload sketch plant_saver.ino to your Arduino board. Don't forget to install a LiquidCrystal_I2C library.
Schematics available in Fritzing format but breadboard part is not done.
SoilWatch 10 part for Fritzing.

Play, modify and adapt to your needs. You can tweak Arduino sketch to suit your plant, soil type and pot size. Hope you enjoyed the project.
