Introduction
Have you ever looked at an electronic device and wondered how it works? Perhaps you've taken a closer look at a circuit board and surveyed the seemingly random bits and pieces soldered to the board and wondered what they all did and how they all work. Maybe you've even said to yourself, How hard can this be? Could I learn how to do this? Welcome to Electronics Fundamentals. My name is Gordon Maretzki, and this course is created for the developer, designer, or inventor who wants to take his creative ideas and work them out into real electronic devices that make the world go around. A foundational understanding of electronics opens the gateway to integrating the digital world with the physical world.

Theory
Here are some basic theoretical ideas in the study of electricity. Understanding them will help us with our projects giving us knowledge to build strong, reliable circuits. In this section, we'll look at exactly what electricity is and then take a look at some basic electric circuits. We'll examine the difference between AC and DC electricity and study the behavior of electricity in a circuit by exploring the properties of voltage, current, and resistance. Then we'll wrap up the theory section with Ohm's Law and the Power Law.

Breadboard Tutorial
In this module, we'll take a look at starting to build some simple circuits using breadboards. Breadboards are handy little devices that let us quickly build circuits. Components are easily inserted into the breadboard and connections quickly made to work up live circuits. A breadboard circuit allows us to swap components and make changes to our circuits for experimentation. We can quickly see the practical effects or changes made and make adjustments to get the circuit performance we are looking for.

Passive Components
It's time to start looking at some specific electronic components that are used to build circuits. We've already looked at a few components--the resistor, the capacitor, LEDs, and the 555 timer. Let's take a closer look at some of the basic building blocks of electronic circuits. You'll find that the vast majority of circuits are built with basic components combined in different fashions to obtain the desired result. Very complex circuits can be broken down to these primary components. Components can be categorized into two basic categories. One is passive and the other is active. A passive component is a component that does not require energy to operate except for what is available in the circuit that it is connected to. The passive component is not capable of power gain and is not a source of energy. In the context of electronic technology, there are stricter guidelines for the term passive component. Electronic engineers view this term usually in correlation with circuit analysis, which involves methods of finding the currents through and the voltages across every component in the network. We're going to use a very loose categorization of components. And, in fact, some of what we are going to consider as passive components could by definition be considered active components. Passive components that we are going to look at include wire and cable, switches, relays, resistors, capacitors, and once we've taken a look at these components, we'll look at a basic resistor capacitor circuit.

Circuit Construction Techniques
When we are working in electronics, we more than likely are trying to build something useful. When all our study and design is done, we'll have to pick a way to physically work out the circuit. We're going to take a look at three different methods--breadboard, perforated board, and printed circuit boards.
