Put simply, the Raspberry Pi is a cheap computer that exposes pins for physical computing. This means that you can attach a wide variety of electronic components to it and drive them from software, The Pi primarily runs a version of the Linux operating system called Raspbian but other operating systems (or even none at all) can also be used to host software applications that you write. Designed and distributed as a cheap device for the purpose of educating folks in the skills of computer programming, it is without question that the Pi is more than powerful enough for a wide variety of projects.
I've been working in the software business for over 30 years but until recently, hadn't been playing directly with Micro Processors. When I bought a Raspberry PI and then an Arduino, I'm afraid I got hooked. In my house I am surrounded by computers of all shapes, sizes and capacities... any one of them with orders of magnitude more power than any of these small devices... however, I still found myself fascinated.
