Visit Gardenbot.org for a collection of tutorials for how to build things (like a soil moisture sensor), software for running GardenBot, resources, links, and more.
To get started, you will want to browse the “How-To” section to see what is required to build the various modules.
The ultimate goal of the GardenBot project is to be a complete garden monitoring and automation system. A key design consideration is to keep everything as easy as possible — especially for users new to Arduino and DIY electronics projects.
GardenBot is currently a work in progress. This project is built upon open source technology, so it is free to be used and modified in any way you see fit (provided you adhere to GardenBot’s license).
