A watering controller that can be home networked using an Arduino

A couple of weeks ago, I published a great little controller module that provided 6 relays able to be controlled from a computer via a network.  After I published it, I got to thinking that the same basic design, with a couple of changes could be pressed into service as a garden watering system controller.  So, I got to work, modified the design, and here you have it...  A sprinkler controller that runs by ...

Bluetooth Controlled Message Droid using Arduino

This is an instructable for a bluetooth controlled Message Droid. I call it R2Blue2. It moves around and displays messages that you type using your phone or computer. Atleast it was supposed to. Due to many problems such as underpowered batteries and bad cable management I wasn't able to extract the performance necessary. I will explain the problems that plagued this build later. The messages are sent over ...
