The Raspberry Pi is a single board computer that welcomes you into the world of programming and electronics. Running a full fledged operating system, the Pi can effectively replace most people's computers! If you're interested in learning high level programming and interacting with the physical world using the Pi's GPIO header, check out my video tutorials. I have over forty video tutorials that range from getting you started with a headless setup to simple circuit control all the way to a full fledged home automation security system.
