Irrduino is an Arduino-based irrigation control system. It includes:
IrrduinoController
A project written in C that runs on the Arduino controller. It was
prototyped using an Android ADK board and an Arduino Ethernet Shield.
IrrduinoDroid
This is an Android application that can control IrrduinoController.
IrrduinoServer
This is a Python, Google App Engine application that can control
IrrduinoController and talk to IrrduinoDroid. It also provides
reporting.
IrrduinoServer/static/dart
This is a game written in Dart called Lawnville that is a bit like
Farmville, but it results in a real lawn being watered.
To use these applications, you'll need to configure some server names. Search for YOUR-SERVER-NAME in the code. See also IrrduinoServer/README.
This project is not an official Google product (experimental or otherwise), it is just code that happens to be owned by Google.
