I want you to have a successful project.

For most home diy projects that require sensors and actuators, the Pi is not the best choice. A Pi is a full blown computer. Its good for calculating really complex things. If you want to take in a live webcam feed and use image recognition to determine the location of something, that's the kind of thing the Pi is good at. Lots of processing, and the hardware connection is a single USB plug.

The Pi is not good at interfacing with sensors and actuators. The Pi doesnt even have any analog inputs. All the signal are 3.3v, whereas many hobby sensors are still 5v. The pins are not broken out in a manner condusive to hooking up random stuff. In general, reading sensors and turning things on and off is extremely easy and does not require much processing at all. Of course its possible to connect sensors and actuators to a Pi, its just not as easy as it could be.

If you have something that requires turning things on and off and doesn't require a lot of processing power, why would you use something that excels at processing power and is hard to connect things to?

An Arduino is really easy to connect things to, especially with all the different shield out there. An Arduino has enough processing power to do some pretty complex turning on and off, it probably has more processing power then you will need.
