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.

https://youtu.be/vN9aR2wKv0U After learning the difference between Voltage, Current, and Power in Episode 4, now we look at a little bit closer type of voltage. 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.

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.

Part 3: Common Circuit Schematics The third part in a three part series on reading Electronic Schematics. Using the Arduino Uno reference design as an example, we look at common circuits we might find when reading a schematic. Part 1: Passive Components Part 2: Active Components

Part 2: Active Component Symbols Schematics are the language used to describe electrical and electronic circuits. To understand how to read them, you need to know how each of the basic symbols look. Part 2 of this 3 part tutorial describes the symbols used for active components like diodes, transistors (BJTs and MOSFETs).
