Electronics-Basics

https://youtu.be/81zNcctopBI What was the first electronic component you played with? It was probably a LED. They’re fun to blink in patterns or learn to fade. Most projects (and products) use them for useful indicators. LEDs add magic to every electronics project. Often not understand is what else you need to make that LED work correctly. Learn what current limiting resistors do for LEDs and watch what happens when you don’t use one.

https://youtu.be/WxJKXGugfh8 We live in a world of analog. Clocks are a great example of how time is continuously changing with nearly infinite precision. However, when you look at a digital clock, there are very specific “digits”. (Get it? Digital… Digits…) Using the analogy of clocks, this TutorialCast explains the basic difference between Analog and Digital Electronics. It ends with a slight twist.

The “C” in “AC” and “DC” stands for “Current.” However, people will commonly say “My home has 120 (or 240) Volts AC.” What the heck? How can AC mean Current and Voltage? This video, we break it down the differences with some simple examples.

https://youtu.be/lYZUXV-v71Y Simplified explanation definitions of Voltage, Current, and Power. These basic electronic terms are all related but have different, specific meanings. This plain-language explanation will help you understand how to use them. This early video had some issues with how I presented concepts. At some point, I’d like to come back and re-do it.
