How Stuff Works: Digital Logic Circuits

What if you want to experiment with Boolean gates and chips? What if you would like to build your own digital devices? Here is a graphical tutorial describes how you can build digital logic circuits using 7400 series TTL gates.

In this article, you will see how you can experiment with all of the gates discussed in the Boolean logic article. We will talk about where you can get parts, how you can wire them together, and how you can see what they are doing. In the process, you will open the door to a whole new universe of technology.
