Phil Tucker had a problem with a local dog and his front lawn with regards to solid waste disposal on the grass. He has come up with a clever solution that relies on an IP camera and an Arduino. When the camera detects motion in a certain area of its' view, it activates a digital output which is read by the Arduino. This in turn activates a relay which powers a solenoid water valve - and turns on the water sprinkler. For example:
Simple yet effective. Hopefully over time this will persuade the dog to do it's business elsewhere. You can read more about the project and design over at Phil's page here. And we're on twitter and Google+, so follow us for news and product updates as well.
