This is the first in a series of guides that will look at digital circuits: what they are, how they work, and how we can make use of them.
We'll start with the basics and build up to more and more powerful circuits, all based on what we've covered in earlier parts of the series. The plan is to end up with a simple 8 bit processor designed, built, and functioning.
As we go, in true maker fashion, we'll build what we need to help in our exploration. Schematics, build videos, parts lists, and where to find everything will be provided so I hope you will follow along and find out what really goes on in that little black chip on your Arduino, Feather, Trinket, or whatever board you use. It's fun and exciting, and it's the building blocks that all of computing is built on. At least until the not too distant future.*
That's where we're headed, but we'll start simply. With numbers.
