Learning Basic Electronics
« on: March 28, 2017, 09:01:13 PM »
I am just beginning to get a real grasp on basic electronics after many years and many false starts.  The good news is you don't need lots of math or an electrical engineering degree to do most of the things you want to do in hobby robotics.

The 80/20 rule (also called The Pareto Principle) assures you will be able to do 80% of the work if you learn 20% of the topic.  So far that seems to be working for me.

I highly recommend the website below.  The electronics text books from allaboutcircuits are frankly the best I have ever read, far better than many I have bought in stores.  If you sign up for the website you can download them as PDFs but if you don't want to sign up you can just read them online.  They are wordy (roughly 400 pages each) but explain the topics in a very clear way with minimal math.  If you can add, subtract, multiply and divide you are good to go.

Next are a couple of other websites that have a lot of material that I found to be helpful.

http://www.electronicshub.org/tutorials/

    http://www.electronics-tutorials.ws/


If you don't want to read a lot of material at start, I found the tutorials at Sparkfun.com very good.  Most of their tutorials involve using the products they sell, but a lot of the early tutorials are very good at explaining the basics.  They also cover some of the ...bench craft... issues that the theoretical texts tend to miss.  Some of my favorites are listed below:

https://learn.sparkfun.com/tutorials/how-to-use-a-multimeter
https://learn.sparkfun.com/tutorials/how-to-use-an-oscilloscope

Frankly, for a fast start you should read the Sparkfun tutorials first, they are short, clear and well written.


Finally, videos can be great.  Following are some of my favorite YouTube channels to help with learning electronics.  Afrotechmod comes especially recommended:

https://www.youtube.com/user/greatscottlab/videos

I hope this proves to be helpful for some of you just getting into the hobby.  Remember when robots take over the world we will be in Charge!
