What is a Raspberry Pi, anyway?

Before we figure out what type of internet connected gadget the Raspberry Pi is, it helps to know what this little computer actually is. Basically, it's a small, single-board computer, meaning everything it needs to run is on one circuit board. It's about the size of a credit card, or even smaller depending on the model, which is pretty neat. You can plug in a keyboard, a mouse, and a screen, just like a regular computer, and it runs a version of Linux, a popular computer operating system. It's often used by hobbyists, students, and even some companies for all sorts of tasks. You know, it's a very versatile little machine.

The folks who created the Raspberry Pi originally wanted to make a low-cost computer to help teach basic computer science in schools. They wanted something that was easy to get, simple to use, and powerful enough for learning. It turns out, this tiny computer became popular far beyond its first goal. People started using it for media centers, retro gaming systems, and, as we're talking about today, for making smart, connected things. It's quite amazing how widely it has been adopted, more or less by everyone.

So, in a way, think of a Raspberry Pi as a very small, yet very capable, general-purpose computer. It has a processor, memory, and ports for connecting other things, just like a bigger desktop machine. The real magic happens when you start connecting it to the internet and other physical objects, which is where its role as an internet connected gadget really shines. It's pretty cool how much it can do, for instance, with just a few simple additions.

A tiny computer, for sure, but what makes it an IoT device?

Now, let's get to the core of it: what makes the Raspberry Pi an internet of things device? The main thing is its ability to interact with the physical world and then send that information over a network, usually the internet. A regular computer is mostly for working with information on a screen, but an internet of things device gathers details from its surroundings, or acts upon them. This is where the Raspberry Pi truly steps up. It has special connection points called GPIO pins, which stands for General Purpose Input/Output. These pins are like little doors that let the Raspberry Pi talk to other bits of hardware.

For example, you can hook up sensors to these pins to measure things like temperature, light, or movement. You can also connect actuators, which are things that can make something happen, like turning on a light or spinning a motor. Once the Raspberry Pi gets information from a sensor, or needs to control something, it can use its built-in Wi-Fi or Ethernet connection to send that information to a cloud service, or receive commands from afar. This capability to sense, act, and communicate is what makes it a prime candidate for an internet connected gadget. It's almost as if it has little feelers and a voice to tell others what it senses.

The fact that it runs a full operating system also means you can write complex programs for it in many different computer languages. This gives you a lot of freedom to create very specific behaviors for your internet connected gadget projects. You're not limited to pre-made functions; you can really shape how it works. This flexibility is a very big reason why it's so popular for those wanting to build their own smart solutions, basically from the ground up.

It's like a blank canvas for building smart things, if you will. So, it really belongs to the "DIY" or "maker" category of internet connected devices.

There are generally a few categories of internet connected gadgets. You have consumer gadgets, like those smart home devices you buy off the shelf. Then there are industrial internet connected gadgets, used in factories and big businesses. The Raspberry Pi can actually be used to make both, but it really shines in the prototyping and custom solution space. It allows people to experiment and build unique items that might not exist otherwise. It's a bit like having a tiny factory for smart ideas right on your desk, which is pretty neat.

Because it's so adaptable, the Raspberry Pi can act as a "hub" for other internet connected devices, collecting data from many different sensors and sending it to the cloud. Or, it can be a "edge device," doing some computing right where the data is gathered, before sending only important bits over the network. This makes it a really valuable piece of kit for anyone wanting to get their hands dirty with creating custom smart setups. It's quite flexible in what role it can play, in some respects.
