Hi, My name is John. I hope you enjoy this little course. So far I have 14 lessons here, and a Basic Electronic Components description page. The first four videos are here for Lesson 3, 4, 5 and 6, more to follow.

You do not need to put your email address or a website or even a name to post a comment. If you do want to leave your name, it might be better for security reasons, to simply put something like Fred B.

Any comments about what you like or don’t like that would help me improve this site would be welcome. Thanks, John

    1. David, I only speak English, but if you were asking what the lessons cost, there are no charges. Just go to and read whatever you want., John

  1. Good day! Do you know if they make any plugins to safeguard against hackers?
    I’m kinda paranoid about losing everything I’ve worked hard on.
    Any tips?

    1. Hi Jenny, I use one called Wordfence Security. Seems to work OK, and it’s free. I guess I’ll never know for sure if it works or not unless I get hacked.

      All we can do is keep backing up our work just in case.


  2. After reading the topic several times, I feel that I need to republish it on my blog. After the admin’s permission, I will share the topic on my personal page. I hope for more useful topics of this type.

  3. I think you and I are about the same age. LEDs came out when I was in high school. As a kid, I read a number of books about electronics theory, and built a couple of things from schematics, but I always wanted to connect the theory with the reality: Why does that circuit work that way?

    Wow! So far, I just looked at the pictures of the components. I am already impressed. I can’t wait to get to the course itself. Thanks!

    1. Hi Jim, it’s just a forward biased diode. When conducting, it heats up and emits light. A process called electroluminescence.

      I think all diodes actually would emit light, but LEDs are engineered specifically to do that, and of course they have a transparent covering.

      Thanks for your positive comment on my component section.

  4. Hmm is anyone else experiencing problems with the pictures on this blog loading? I’m trying to determine if its a problem on my end or if it’s the blog. Any suggestions would be greatly appreciated.

  5. Posted a new video for lesson 4, Ohms Law part one. It goes over the calculations involved in a series resistor circuit. The calculations are explained step by step so a fourth grader could easily understand.

    Then, after the calculations are complete, a meter is hooked up to show what the actual readings were.

    Sorry for the delay,



  6. Due to having major surgery, I will not be able to add any more videos until probably mid to late September, God willing. Thank you.

  7. In Basic Electricity, you displayed a model of an atom to display the setup of a basic atom of Hydrogen. However, the atom is described as (and displayed in picture) an atom of Helium, with 2 electrons, 2 protons, and 2 neutrons. The Hydrogen atom has 1 proton, 1 electron, and no neutrons, only isotopes have it. Can you clarify

    1. Asterwind, THANK YOU!!

      You are of course, absolutely right! I had an image of a Hydrogen atom at first, but it wasn’t one I felt good about using. The images I use here all all either from Wikipedia, with a Creative Commons license, or created by me. So when I couldn’t find a Hydrogen atom on Wiki, I changed the image along with the description of how many protons, neutrons, and electrons, but forgot to change the name from Hydrogen to Helium.

      I must apologize to my readers for that and credit Asterwind for catching my mistake. Good job Asterwind!

  8. The rest of the lessons for THIS Basic Beginners course are now all online. The FUN STUFF will be experiments shown on videos, and I am just starting them. They will start showing up by July 31.

    After that I plan on starting more lessons taking things to the next level. Thanks for looking, John
