There are roads, buildings, cars, and people all connected in a complete system. And the higher you go, the more you start to see just how your city is organized and meticulously planned.

As you climb higher and higher, you get a new perspective on a city that you only see from the great heights. My favorite part of the journey is when the plane takes off from the runway. Look at a PCB from 10,000 feet, and you’ll find that it looks just like a city!Īlthough not lately, likely you’ve flown in an airplane at least once in your life. But with a high-altitude perspective, understanding what a PCB is and how it works can be easy.

There’s a ton of different looking components, and so much to learn to know how it all works together. To the electronics beginner, these green shapes can seem a bit mysterious at first. Why? These boards are in every piece of electronics known to man, no exceptions! Open your computer, smartphone, or even a fork, and you’ll find a PCB. If you have even a little bit of interest in learning about electronics, then you absolutely need to know about the printed circuit board or the PCB.
