Home built test console for ATMEGA168 Arduino
Practical Electronics and Electricity for Learning and Fun
by Lewis Loflin
Introduction These pages were originally setup to assist my electricity and electronics students at a local community college. As of 2009 this will be greatly expanded. The goal will be to expand interest at both the hobby level and practical level. This will target not only my students, but those interested in practical devices and ideas we can build at low cost in an average home or workshop. I'll also include links to other websites and specification sheets for the parts used.
This will be limited to items built, tested, and demonstrated in class. This is not a full scale electronics class, but an introduction on the basic electricity level. I'll avoid most of the complex math and stick to basics. This will be from a practical hands on approach that can produce real things one can easily build and see.
As in my classes, students come in with all kinds of skill levels and have often been out of formal school for years. They often work in industry doing real things. Most do far better with "hands on" than just theory alone. Other than those few that are just lazy, most do very well at grasping complex subjects if they see it working. So I take an approach of breaking the concepts down into small subjects and then combining them into more complex systems.
Our textbook will be Electrical Studies for Trades by Stephen L. Herman. (3rd Edition) The book isn't necessary for the material here, but will help. My E-Mail lewis@sullivan-county.com Phone: 276-669-0565 if anyone has any questions.
