This post starts with two facts:
1. I have a penchant for killing plants.
2. People in Holland grow things really well indoors.
After reading about how well things can grow indoors, I started thinking that maybe automation was my path to healthy plants. So I decided to build the bare minimum - get a plant, a pump, and a water sensor. When the water sensor says "no water here", use the pump to put water there.
I also decided to run it all through a Raspberry Pi to as an excuse to interact with the RPi GPIO.
Here's how I did it!
