Building Circuits in Lab§
- Two brief descriptions of breadboards and how to use them to build circuits: 1, 2.
- Fritzing is software that aids in the design of electronic circuits. Among many other features, it has a tool for laying out circuits on a breadboard, letting you work with a design before wiring it up in the lab.
Concepts§
- The Binary Number System — a very quick explanation of how binary numbers work, including fractions. There's a slightly longer explanation from a different perspective here.
