https://youtu.be/px8cUUbxnr0 There have been so many good questions coming in lately that I decided to take a break from normal topics and answer 3. Not sure the right frequency yet, but will probably do this every couple of episodes/videos.

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. The most common…
https://youtu.be/7vhvnaWUZjE Trying to decide between an Arduino or Raspberry Pi for your project? In this video we look at what the difference between the two boards are and talk about what kinds of projects each are best at. Episode Notes This one has been a long time in the making for two reasons. First, I spent some time creating an opening sequence for the videos. Thanks to everyone who helped me decide on the right…
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.
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.

Part 3: Common Circuit Schematics https://www.youtube.com/watch?v=VfkSzvXPYak 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 ComponentsPart 2: Active Components
Part 2: Active Component Symbols https://www.youtube.com/watch?v=CpL5omjyfww 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). Part 1: Passive ComponentsPart 3: Arduino Schematic
Schematics Part 1: Passive Component Symbols Schematics are the language used to describe electrical and electronic circuits.
