This course is an introduction to hobby electronics with a focus on building your own small projects. It is part of the Discover Electronics kit available here.
To take full advantage of this course watch some of the videos all of the way through before you start. As the course progresses I will add more resources to this site as well as assignments for you to complete.
The course group has a forum as well as a documents section that we will use for additional materials. In your profile you will find a place to upload photos you would like to share.
With lesson one the idea is to get familiar with some of the basic concepts and terminology as well as the solderless breadboard.
All matter is made of atoms. Atoms are made up of tiny particles we call electrons, protons and neutrons. Protons and, usually, neutrons form the center (nucleus) of the atom. Electrons spin around the nucleus.
All matter is made up of these few parts. It is only the number and arrangement of the particles that makes one type of matter different from another.
These particles can have an electrical charge. Protons have a positive electrical charge and electrons have a negative electrical charge. Positive and negative are attracted to one another while like charges repel one another.

For this lesson we continue to get familiar with the basics of volts, amps, and ohms. We will look at a voltage divider, the difference between series and parallel, and Ohm’s law.
It is probably best to review some of the previous videos before continuing.
