I purchased a Raspberry Pi this summer but I wasn’t sure exactly what I wanted to do with it. A couple of weeks ago I finally found the inspiration I was looking for when I ran across someone using a Pi to control his sprinkler system.
The site seems to be down at the moment but in case it comes back up here is a link http://badgerbooth.com/
I purchased the Pi Cobbler Breakout kit from Adafruit. (http://www.adafruit.com/products/914) and have successfully been able to turn LEDs on and off with bash and using the GPIO php script from Badger Booth.
I think I’ll rewrite the php model to clean up some of the initialization. Once I get it working well enough, I’ll post it here.
