electronics basics


https://youtu.be/EQtwsWJuUPs Understanding voltage dividers means understanding Ohm’s Law.  A common use for a voltage divider in most projects is to monitor a battery.  Say you are powering your circuit with a 9V or 12V battery. Microcontroller boards don’t do well with those voltages.   In a future video, we’ll come back and look at more circuits that can use voltage dividers. Episode Notes Correction: There is a mistake around 3:00.  I say “91 millivolts” and I should…

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.
